Mother of the Believers, Lady Aisha Siddiqa (may Allah be pleased with her) narrates: I saw the Messenger of Allah (peace and blessings be upon him) in the state of death, and there was a bowl of water placed near him. He would put his blessed hand into the bowl and then wipe his radiant face with the water and say: "O Allah! Help me in the agonies of death," or he said, "Help me in the unconsciousness of death."
