In the name of God, Most Gracious, Most Merciful
O you who believe, do not raise your voices above the voice of the prophet,* nor shall you shout at him as you shout at each other, lest your works become nullified while you do not perceive.
*49:2 Whenever the word "prophet" (Nabi) is used in reference to Muhammad, it invariably refers to him during his life, not after his death. Obviously, we cannot possibly raise our voices above Muhammad's voice, now that he is dead. See also 33:56.
Investigate Rumors Before Believing Them
Reconcile The Believers
If two groups of believers fought with each other, you shall reconcile them. If one group aggresses against the other, you shall fight the aggressing group until they submit to GOD's command. Once they submit, you shall reconcile the two groups equitably. You shall maintain justice; GOD loves those who are just.
The Real Family
Believers Set the Example
O you who believe, no people shall ridicule other people, for they may be better than they. Nor shall any women ridicule other women, for they may be better than they. Nor shall you mock one another, or make fun of your names. Evil indeed is the reversion to wickedness after attaining faith. Anyone who does not repent after this, these are the transgressors.
Suspicion Is Sinful
O you who believe, you shall avoid any suspicion, for even a little bit of suspicion is sinful. You shall not spy on one another, nor shall you backbite one another; this is as abominable as eating the flesh of your dead brother. You certainly abhor this. You shall observe GOD. GOD is Redeemer, Most Merciful.
