No one can harm anyone without God's approval!

Verse 11 of Chapter 64:

No misfortune befalls except by Allah's command; and Allah will guide the heart of whoever accepts faith in Him; and Allah knows all things.

Verses 22-23 of Chapter 57:

There is no misfortune that reaches in the earth or in your selves but is mentioned in a Book, before We initiate it; indeed this is easy for Allah. So that you may not be saddened upon losing something, nor rejoice upon what you are given; and Allah does not like any boastful, conceited person.

God did not allow believers to make friendship with those  who removed them from their homes and possessed the intention  to harm them!

Verses 1-3 of Chapter 60:

O you who have believed, if you have come out (from your homes and emigrated) in order to fight in My way and to seek My goodwill, then do not make friends with My enemies and your enemies. You show them friendship even though they have refused to believe in the Truth that has come to you, while they drive out the Messenger and you away only because you believe in Allah, your Lord. You send them friendly messages secretly, whereas I know full well whatever you do secretly and whatever you do openly. Whoever from among you does so, has indeed gone astray from the right way. If these people overcome you, they will be enemies to you and will use their hands and their tongues to harm you. They wish that you should turn unbelievers somehow. On the Day of Resurrection neither will your relationships avail you anything nor your children. Allah on that Day shall cause separation between you, and He is Seer of whatever you do.

Verses 8-9 of Chapter 60:

Allah does not forbid you to treat kindly and act equitably towards those who have neither fought you in the matter of religion nor driven you out of your homes. Indeed Allah loves the just. He only forbids you to take for friends those who fought you in the matter of religion, and drove you out of your homes, and cooperated with others in your expulsion. Those who take them for friends are indeed the wrongdoers.

God has the knowledge of everything in the heavens and the earth!

Verse 7 of Chapter 58:

Are you not aware that Allah has the knowledge of everything in the heavens and the earth? It cannot be that three men whisper together and Allah is not the fourth of them or five men whisper together and Allah is not the sixth of them. Whether they are fewer than this or more, Allah is with them wherever they are. Then, on the Day of Resurrection, He will tell them what they have done. Allah has the knowledge of everything. 

What is the condition to be met after performing both the Umrah and the Hajj? 

Verse 196 of Chapter 2:
And complete Hajj and `Umrah for Allah. But if you are prevented, then sacrifice a Hady that you can afford, and do not shave your heads until the Hady reaches the place of sacrifice. And whosoever of you is ill or has an ailment on his scalp (necessitating shaving), he must pay a Fidyah (ransom) of either fasting or giving Sadaqah or a sacrifice. Then if you are in safety and whosoever performs the `Umrah (in the months of Hajj), before (performing) the Hajj, he must slaughter a Hady such as he can afford, but if he cannot (afford it), he should fast for three days during Hajj and seven days after his return, making ten days in all. This is for him whose family is not present at Al-Masjid Al-Haram (i.e., non-resident of Makkah). And fear Allah much and know that Allah is severe in punishment.

Actual believers must preach to other people not to commit evil deeds!

Verses 163-166 of Chapter 7:
And ask them (O dear Prophet Mohammed - peace and blessings be upon him) of the township that was by the sea; when they used to exceed in the matter of the Sabbath - when their fish used to come swimming atop the water in front of them on the day of Sabbath and not come on the days it was not Sabbath; this is how We used to test them, due to their disobedience. And when a group among them said, "Why do you preach to a people whom Allah is going to destroy or mete out a severe punishment?" They said, "To have an excuse before your Lord, and that perhaps they may fear." And when they forgot the advices they had been given, We rescued those who forbade evil, and seized the unjust with a dreadful punishment - the recompense of their disobedience. Consequently when they rebelled against the command to refrain, We said to them, "Be apes, despised!"

Does God not allow believers to marry disbelieving women regardless of whether they are from those who  received His books earlier or not?

Verse 221 of Chapter 2:
And do not marry polytheist women until they become Muslims; for undoubtedly a Muslim bondwoman is better than a polytheist woman, although you may like her; and do not give your women in marriage to polytheist men until they accept faith; for undoubtedly a Muslim slave is better than a polytheist, although you may like him; they invite you towards the fire; and Allah invites towards Paradise and forgiveness by His command; and explains His verses to mankind so that they may accept guidance.

Verse 5 of Chapter 5:
This day the pure things are made lawful for you; and the food of the People given the Book(s) is lawful for you - and your food is lawful for them* - and likewise are the virtuous Muslim women and the virtuous women from the people who received the Book(s)* before you when you give them their bridal money - marrying them, not committing adultery nor as mistresses; and whoever turns a disbeliever after being a Muslim, all his deeds are wasted and he will be among the losers in the Hereafter.

* 'and your food is lawful for them' could be relevant only to those only who had been Muslims (or, actual followers of the holy Book(s)) before the last prophet came and thus accepted  Al-Qur'an and the last prophet when he came. Relating the word 'them' to the Jews and Christians who were disbelievers (i.e,, who did not accept  Al-Qur'an and/or the last prophet) is not justifiable. 

* 'the virtuous women from the people who received the Book(s)' indicate those who were believers  (or, actual followers of the holy Book(s)) before the last prophet came, and later, accepted  Al-Qur'an and the last prophet.

Verse 10 of Chapter 60:

O you who have believed, when the believing women come to you as emigrants, examine and test (their faith), although Allah only knows best the truth of their faith. Then, when you find them to be true believers, do not return them to the disbelievers. Neither are they lawful for the disbelievers nor are the disbelievers lawful for them. Return to their disbelieving husbands the dowers that they had given them; and there is no blame on you if you marry them when you have paid them their dowers. And you also should not hold back unbelieving women in marriage. Ask for the dowers that you had given to your unbelieving wives, and let the disbelievers ask for the dowers that they had given to their Muslim wives. This is Allah's command: He judges between you, and He is All-Knowing, All-Wise. 

When would the souls be reunited with the regenerated human bodies in the graves?

Verses 1-14 of Chapter 81:
When the sun is folded up, and when the stars scatter, and when the mountains are set in motion, and when the ten month pregnant she-camels are left untended, and when the beasts are gathered together, and when the oceans are set ablaze, and when the souls are reunited (with their bodies), and when the infant girl, buried alive, is asked for what crime she was slain, and when the records are unfolded, and when the veil of heaven is removed,and when Hell is set blazing, and when Paradise is brought near, then each person shall know what he has brought with him.

Verses 1-5 of Chapter 82:
When the heaven is cleft asunder, and when the stars scatter, and when the seas are torn apart, and when the graves are laid open. Then every person shall know all his works, the former and the latter.

What will people feel on the Day of Judgement after having been raised up from their respective graves?

People will feel that they have slept for hours only in the graves!

Verses 51-52 of Chapter 36:

And the Trumpet will be blown and behold from the graves they will come out quickly to their Lord. They will say: "Woe to us! Who has raised us up from our place of sleep.'' (It will be said to them): "This is what the Most Gracious had promised, and the Messengers spoke truth!''

Verse 259 of Chapter 2:

Or take the case of the one who passed by a township that had fallen down upon its roofs. He exclaimed, "How shall Allah bring back to life this township that has become dead?" At this Allah caused him to die and he lay dead for a hundred years. Then Allah brought him back to life and asked him, "How long have you lain here?" He answered. "I might have lain here for a day or a few hours." Allah said, "Nay, you have been lying here in this state for a hundred years: now, just have a look at your food and your drink; they have not become spoiled in the least. Then have a look at your ass, (and see that his very bones have become rotten) and We have done this in order to make you a Sign for the people. Look, how We raise up the skeleton and set the bones (of the ass) and cover them with flesh and (put breath of life into them)." And when the Reality became manifest to him, he said, "I know that Allah has power over everything."

Verse 19 of Chapter 18:

And similarly We awakened them so that they may enquire about each other; a speaker among them said, "How long have you stayed here?" Some among them said, "We have stayed a day or part of a day"; the others said, "Your Lord well knows how long you have stayed; therefore send one of you to the city with this silver coin - he may then check which food available there is purer, in order to bring some of it for you to eat - and he must be courteous and not inform anyone about you."

Does God never make the reward of the good doers to be lost in this world?

Verse 56 of Chapter 12:
Thus did We give established power to Joseph in the land, to take possession therein as, when, or where he pleased. We bestow of our Mercy on whom We please, and We suffer not, to be lost, the reward of those who do good.

Does God bestow special favor upon the poor people as well as the true believers?

Verses 79-82 of Chapter 18:
As for the boat, it belonged to poor people working in the sea. So I wished to make a defective damage in it, as there was a king behind them who seized every boat by force. And as for the boy, his parents were believers, and we feared he would oppress them by rebellion and disbelief. So we intended that their Lord should exchange him for them for one better in righteousness and nearer to mercy. And as for the wall, it belonged to two orphan boys in the town; and there was under it a treasure belonging to them; and their father was a righteous man, and your Lord intended that they should attain their age of full strength and take out their treasure as a mercy from your Lord. And I did them not of my own accord. That is the interpretation of those (things) over which you could not be patient.

How did Prophet Moses and his followers respond to the oppression carried out by King Fir`awn?

Verses 127-129 of Chapter 7:
The chiefs of Fir`awn's people said: "Will you leave Musa and his people to spread mischief in the land, and to abandon you and your gods'' He said: "We will kill their sons, and let their women live, and we have indeed irresistible power over them.'' Musa said to his people: "Seek help in Allah and be patient. Verily, the earth is Allah's. He gives it as a heritage to whom He wills of His servants; and the (blessed) end is for the pious and righteous persons.'' They said: "We suffered troubles before you came to us, and since you have come to us.'' He said: "It may be that your Lord will destroy your enemy and make you successors on the earth, so that He may see how you act''

What is the best garment for human beings?

Verse 26 of Chapter 7:
O Children of Adam! We have bestowed Libas (raiment) upon you to cover yourselves with, and as Rish (adornment); and the Libas (raiment) of Taqwa, that is better. Such are among the Ayat of Allah, that they may remember.

Each of the living creatures has its own community as humans belong to one!

Verse 38 of Chapter 6:
There is not a moving creature on earth, nor a bird that flies with its two wings, but are communities like you. We have neglected nothing in the Book, then unto their Lord they shall be gathered.

Why did God decide hypocrisy for some people?

Verses 1-3 of Chapter 63
When the hypocrites come to you, they say: "We bear witness that you are indeed the Messenger of Allah.'' Allah knows that you are indeed His Messenger, and Allah bears witness that the hypocrites are liars indeed. They have made their oaths a screen. Thus they hinder (others) from the path of Allah. Verily, evil is what they used to do. That is because they believed, and then disbelieved; therefore their hearts are sealed, so they understand not.

After a decision is made by proper consultation, trust should be put in God!

Verse 159 of Chapter 3:
And by the mercy of Allah, you dealt with them gently. And had you been severe and harsh-hearted, they would have broken away from about you; so pardon them, and ask forgiveness for them; and consult them in the affairs. Then when you have taken a decision, put your trust in Allah, certainly, Allah loves those who put their trust (in Him).

Remembrance of God during the payers and other time makes the most significant impact on a life!

Verse 45 of Chapter 29:
Recite what is sent of the Book by inspiration to thee, and establish regular Prayer: for Prayer restrains from shameful and unjust deeds; and remembrance of Allah is the greatest (thing in life) without doubt. And Allah knows the (deeds) that ye do.

What protect people from the evil invitation of Satan?

Verses 98-100 of Chapter 16:
And when you recite the Qur’an, seek the refuge of Allah from Satan the outcast. Indeed he has no power over the believers and who rely only upon their Lord. Satan’s power is only over those who make friendship with him and ascribe him as a partner (in worship).

There are angels deployed in succession to guard and protect human beings from dangers  not seriously ordained under the Will of God!

God does not change the good condition of a people as long as they do not change their state of goodness!

Verse 11 of Chapter 13:
For him (each person), there are angels in succession, before and behind him. They guard him by the command of Allah. Verily, Allah will not change the (good) condition of a people as long as they do not change their state (of goodness) themselves. But when Allah wills a people's punishment, there can be no turning it back, and they will find besides Him no protector.

People who desire the life of this world and its comforts receive the full rewards for their deeds, with nothing left except the fire in the hereafter!

Verses 15-16 of Chapter 11: 
Whoever desires the life of this world and its comforts, We shall give them the full reward for their deeds in it, and not make any reduction in it. These are the ones for whom there is nothing in the Hereafter except the fire; and all that they did there has gone to waste and all their deeds are destroyed.

When do people become ungrateful and boastful? Who are free from this?

Verses 9-11 of Chapter 11: 
And if We bestow man the enjoyment of some mercy from Us and later withdraw it from him; surely he is most despairing, ungrateful. And if We bestow upon him the enjoyment of a favour after a misfortune that had befallen him, he will surely say, "The evils have gone away from me"; indeed he is jubilant, boastful. Except those who patiently endured and did good deeds; for them is forgiveness, and a great reward.

Everything in the universe has been created in order to test mankind!

Verse 7 of Chapter 11:

And it is He Who created the heavens and the earth in six days - and His Throne was upon the water - so that He might test you, as to who among you have the best deeds ; and if you (O dear Prophet Mohammed - peace and blessings be upon him) say, "Indeed you will be raised again after death", the disbelievers will surely say, "This is nothing but clear magic."
