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."
