Sayyiduna Abdullah bin Amr (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) mentioned the trial of the grave, so Sayyiduna Umar bin Khattab (may Allah be pleased with him) asked: O Messenger of Allah (peace and blessings be upon him)! Will our intellects be returned to us? The Prophet (peace and blessings be upon him) said: Yes, just as you are today. So he said: There is a restriction on his mouth.
