Ibn 'Abbas said, "I spent the night at the house of my aunt. Maymuna. The Prophet, may Allah bless him and grant him peace, got up to answer a call of nature and then washed his hands and face and slept. Then he got up and took the water-skin and loosened its strap and then did a medium sort of wudu' and no more but he did it adequately. Then he prayed. I stood up and went slowly, not wanting him to see that I was observing him. I did wudu'. Then he stood up to pray and I stood at his left. He took my hand and brought me around to his right. His complete night prayer consisted of twelve rak'ats. Then he lay down and went to sleep until he snored. When he slept, he would snore. Bilal gave the adhan for the morning prayer and he prayed without doing wudu'. One of his supplications was, 'O Allah, put light in my heart and light in my hearing and light on my right and light on my left and a light above me and a light behind me and a light in front of me and a light behind him and make my light great.'"
