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.

49:10The believers are brothers, so reconcile between your brothers, and remain conscious of God, so that you may receive mercy.

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.
