49:7And know that among you is the Messenger of God. Had he obeyed you in many things, you would have suffered hardship. But God has given you the love of faith, and adorned it in your hearts, and made disbelief, mischief, and rebellion hateful to you. These are the rightly guided.

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.
