2:129Our Lord, and raise up among them a messenger, of themselves, who will recite to them Your revelations, and teach them the Book and wisdom, and purify them. You are the Almighty, the Wise.”

2:174Those who conceal what God revealed in the Book, and exchange it for a small price—those swallow nothing but fire into their bellies. And God will not speak to them on the Day of Resurrection, nor will He purify them, and they will have a painful punishment.
