Sayyiduna Abdullah ibn Abbas (may Allah be pleased with them both) narrated that I spent a night at the house of Sayyidah Maymunah (may Allah be pleased with her). The Prophet Muhammad (peace and blessings be upon him) got up, and after fulfilling his natural needs, he washed his face and then washed both his hands, and then he lay down again. After that, he stood up and went to the water-skin and opened its mouth, then performed a moderate ablution (neither with excess nor with too little water, washing each part three times), but made sure the water reached everywhere. Then he prayed. I also stood up and remained behind him, because I did not want the Messenger of Allah (peace and blessings be upon him) to think that I was waiting for him. I had also performed ablution. When the Prophet (peace and blessings be upon him) stood up to pray, I stood on his left side, but he took hold of my ear and made me stand on his right side. I completed thirteen rak‘ahs of prayer following the Messenger of Allah (peace and blessings be upon him). After that, he lay down and his breathing became audible. When the Messenger of Allah (peace and blessings be upon him) used to sleep, his breathing would become audible. After that, Sayyiduna Bilal (may Allah be pleased with him) informed him of the prayer, so he prayed without performing a new ablution. The Messenger of Allah (peace and blessings be upon him) used to say in his supplication: O Allah, place light in my heart, place light in my sight, place light in my hearing, place light on my right, place light on my left, place light above me, place light beneath me, place light in front of me, place light behind me, and grant me light. Kurayb (the narrator of the hadith) said that there were seven (mentions of light) in the chest. Then I met a son of Sayyiduna Abbas, and he told me about them, saying: my sinews, my flesh, my blood, my hair, and my skin (fill all of them with light), and he mentioned two more things.
