Yahya related to me from Malik from Hisham ibn Urwa from his father from A'isha, the wife of the Prophet, may Allah bless him and grant him peace, that the Messenger of Allah, may Allah bless him and grant him peace, said, "If you are drowsy in prayer, sleep until sleep leaves you, because if you pray while you are drowsy, you do not know whether you may intend to ask for forgiveness but (in fact) ask for harm."
Muwatta Malik Book 7, Hadith 3
← Previous Hadith Yahya related to me from Malik from Abu'nNadr, the mawla of Umar ibn 'Ubaydullah, from Abu Salama ibn Abd ar-Rahman that A'isha, the wife of the Prophet, may Allah bless him and grant him peace, said, "I was sleeping in front of the Messenger of Allah, may Allah bless him and grant him peace, and my feet were in his qibla. When he prostrated, he nudged me and I pulled up my feet,and when he stood up I spread them out." She added, "There were no lamps in the house at that time."

Muwatta Malik Book 7, Hadith 2 Next Hadith → Yahya related to me from Malik from Ismail from Ibn Abi Hakim that he had heard that the Messenger of Allah, may Allah bless him and grant him peace, heard a woman praying at night. He said, "Who is that?" and someone said to him,"It is al-Hawla bint Tuwayt, she does not sleep in the night." The Messenger of Allah, may Allah bless him and grant him peace, disapproved of that and his disapproval showed in his face. Then he said, "Allah, the Blessed and Exalted, does not become weary, but you become weary. Take on whatever is within your capability."
