Surat Al-Ĥujurāt (The Rooms) - سورة الحجرات

: O you who believe! If a rebellious evil person comes to you with a news, verify it, lest you harm people in ignorance, and afterwards you become regretful to what you have done.

: And know that, among you there is the Messenger of Allah (SAW). 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 SAW) hateful to you. These! They are the rightly guided ones,

: (This is) a Grace from Allah and His Favour. And Allah is All-Knowing, All-Wise.

: 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.

: The believers are nothing else than brothers (in Islamic religion). So make reconciliation between your brothers, and fear Allah, that you may receive mercy.

: 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.).

: 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.
