49:2O you who believe! Do not raise your voices above the voice of the Prophet, and do not speak loudly to him, as you speak loudly to one another, lest your works be in vain without you realizing.

49:9If two groups of believers fight each other, reconcile between them. But if one group aggresses against the other, fight the aggressing group until it complies with God’s command. Once it has complied, reconcile between them with justice, and be equitable. God loves the equitable.

49:11O 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 slander one another, nor shall you insult one another with names. Evil is the return to wickedness after having attained faith. Whoever does not repent—these are the wrongdoers.

49:15The believers are those who believe in God and His Messenger, and then have not doubted, and strive for God’s cause with their wealth and their persons. These are the sincere.
