49:1O you who believe! Do not place your opinions above that of God and His Messenger, and fear God. God is Hearing and Knowing.

49:12O you who believe! Avoid most suspicion—some suspicion is sinful. And do not spy on one another, nor backbite one another. Would any of you like to eat the flesh of his dead brother? You would detest it. So remain mindful of God. God is Most Relenting, Most Merciful.

49:14The Desert-Arabs say, “We have believed.” Say, “You have not believed; but say, ‘We have submitted,’ for faith has not yet entered into your hearts. But if you obey God and His Messenger, He will not diminish any of your deeds. God is Forgiving and Merciful.”

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.
