Yahya ibn Rashid reported: We went to meet with Abdullah ibn Umar and when he came out, he said to us: I heard the Messenger of Allah, peace and blessings be upon him, say, “Whoever withholds his intercession regarding other than the legal punishments prescribed by Allah, then Allah will oppose him; and whoever knowingly argues for falsehood, then he will never be free of Allah’s displeasure until he stops; and whoever says something about a believer that is untrue, then Allah will lodge him in a hole of mud until he repents from what he said.”
