God accepts the sacrifice (for Him) only from those who have taqwa (fear for God in every action)!

Verses 27-28 of Chapter 5:

And recite to them the story of the two sons of Adam in truth; when each offered a sacrifice, it was accepted from the one but not from the other. The latter said to the former: "I will surely, kill you.'' The former said: "Verily, Allah accepts only from those who have Taqwa. "If you do stretch your hand against me to kill me, I shall never stretch my hand against you to kill you, for I fear Allah; the Lord of all that exists.''

Whom does God bring out of darkness into light and guide to the straight path?

Verses 15-16 of Chapter 5:

O People of the Scripture! Now has come to you Our Messenger explaining to you much of that which you used to hide from the Scripture and passing over much. Indeed, there has come to you from Allah a light and a plain Book. Wherewith Allah guides all those who seek His Pleasure to ways of peace, and He brings them out of darkness by His permission unto light and guides them to a straight path.

Does God suffice for those who fear Him (have Taqwa) and put trust in Him alone?

Verse 11 of Chapter 5:

O Believers, recall to mind the favor which Allah has (recently) shown to you: when some people intended to do harm to you, Allah restrained their hands from you. Fear Allah in whatever you do for the Believers should put their trust in Allah alone.

Believers must ensure the justice everywhere in life because it is akin to Taqwa (fear for God)!

Verses 8-10 of Chapter 5:

O you who believe! Stand out firmly for Allah as just witnesses; and let not the enmity and hatred of others make you avoid justice. Be just, that is nearer to Taqwa; and have Taqwa of Allah. Verily, Allah is Well-Acquainted with what you do. Allah has promised those who believe and do deeds of righteousness, that for them there is forgiveness and a great reward (i.e. Paradise). And they who disbelieve and deny Our Ayat are those who will be the dwellers of the Hell-fire.

How to purify oneself prior to offering prayers!

Verse 6 of Chapter 5:

O Believers, when you rise to offer the Salat, you must wash your faces and hands and arms up to the elbows and wipe your heads with wet hands and wash your feet up to the ankles; and if you have become unclean, cleanse yourselves with a full bath; if, however, you are sick or are on a journey, or if any of you has relieved himself or if you have "touched" women and you can find no water, then cleanse yourselves with pure dust: strike your palms on it and wipe your hands and faces with it. Allah does not will to make life hard for you, but He wills to purify you and complete His blessing upon you so that you may show gratitude.

What will be the fate of the people who believe in some messengers of God and reject others?

Verses 150-152 of Chapter 4:

Verily, those who disbelieve in Allah and His Messengers and wish to make distinction between Allah and His Messengers saying, "We believe in some but reject others,'' and wish to adopt a way in between. They are in truth disbelievers. And We have prepared for the disbelievers a humiliating torment. And those who believe in Allah and His Messengers and make no distinction between any of them (Messengers), We shall give them their rewards; and Allah is Ever Forgiving, Most Merciful.

Testimony must be given for the sake of God even though it is against ourselves, our parents or relatives!

Verse 135 of Chapter 4:

O Believers, be you the standard-bearers of justice and witnesses for the sake of Allah, even though your justice and your evidence might be harmful to yourselves, or to your parents, or to your relatives. It does not matter whether the party concerned is rich or poor: Allah is their greater well-wisher than you; therefore, do not follow your own desire lest you should deviate from doing justice. If you distort your evidence or refrain from the truth, know it well that Allah is fully aware of what you do.

Believers must adhere to Al-Qur'an and the Sunnah (teachings & practices) of the last prophet!

 

Verses 58-59 of Chapter 4:

(O Muslims), Allah enjoins you to give the trusts into the care of those persons who are worthy of trust and to judge with justice, when you judge between the people. Excellent is the counsel that Allah gives you, for Allah hears everything and sees everything. O Believers, obey Allah and obey the Messenger and those entrusted with authority from among you. Then if there arises any dispute about anything, refer it to Allah and the Messenger, if you truly believe in Allah and the Last Day. This is the only right way and will be best in regard to the end.

Who among the believers must be trusted and obeyed by other believers?
