1. O you who believe! Do not put (yourselves) forward before Allah and His Messenger (), and fear Allah. Verily! Allah is All-Hearing, All-Knowing.
2. O you who believe! Raise not your voices above the voice of the Prophet (), nor speak aloud to him in talk as you speak aloud to one another, lest your deeds may be rendered fruitless while you perceive not.
7. And know that, among you there is the Messenger of Allah (). If he were to obey you (i.e. follow your opinions and desires) in much of the matter, you would surely be in trouble, but Allah has endeared the Faith to you and has beautified it in your hearts, and has made disbelief, wickedness and disobedience (to Allah and His Messenger ) hateful to you. These! They are the rightly guided ones,
9. And if two parties or groups among the believers fall to fighting, then make peace between them both, but if one of them rebels against the other, then fight you (all) against the one that which rebels till it complies with the Command of Allah; then if it complies, then make reconciliation between them justly, and be equitable. Verily! Allah loves those who are equitable.
11. O you who believe! Let not a group scoff at another group, it may be that the latter are better than the former; nor let (some) women scoff at other women, it may be that the latter are better than the former, nor defame one another, nor insult one another by nicknames. How bad is it, to insult one’s brother after having Faith [i.e. to call your Muslim brother (a faithful believer) as: “O sinner”, or “O wicked”, etc.]. And whosoever does not repent, then such are indeed Zalimun (wrong-doers, etc.).
12. O you who believe! Avoid much suspicions, indeed some suspicions are sins. And spy not, neither backbite one another. Would one of you like to eat the flesh of his dead brother? You would hate it (so hate backbiting) . And fear Allah. Verily, Allah is the One Who accepts repentance, Most Merciful.
13. O mankind! We have created you from a male and a female, and made you into nations and tribes, that you may know one another. Verily, the most honourable of you with Allah is that (believer) who has At-Taqwa [i.e. one of the Muttaqun (pious – see V.2:2)]. Verily, Allah is All-Knowing, All-Aware.
14. The bedouins say: “We believe.” Say: “You believe not but you only say, ‘We have surrendered (in Islam),’ for Faith has not yet entered your hearts. But if you obey Allah and His Messenger (), He will not decrease anything in reward for your deeds. Verily, Allah is Oft-Forgiving, Most Merciful.”
15. Only those are the believers who have believed in Allah and His Messenger, and afterward doubt not but strive with their wealth and their lives for the Cause of Allah. Those! They are the truthful.
17. They regard as favour upon you (O Muhammad ) that they have embraced Islam. Say: “Count not your Islam as a favour upon me. Nay, but Allah has conferred a favour upon you, that He has guided you to the Faith, if you indeed are true.
18. Verily, Allah knows the unseen of the heavens and the earth. And Allah is the All-Seer of what you do.
