Muwatta Malik Book 7, Hadith 9
Yahya related to me from Malik from Said ibn Abi Said al-Maqburi
from Abu Salama ibn Abd ar-Rahman ibn Awf that he asked A'isha, the
wife of the Prophet, may Allah bless him and grant him peace, what the
prayer of the Messenger of Allah, may Allah bless him and grant him
peace, was like during Ramadan. She said, "The Messenger of Allah, may
Allah bless him and grant him peace, did not go above eleven rakas in
Ramadan or at any other time. He prayed four - do not ask me about
their beauty or length. Then he prayed another four - do not ask me
about their beauty and length. Then he prayed three."
A'isha
continued, "I said, 'Messenger of Allah, are you sleeping before you
do the witr?' He said, A'isha, my eyes sleep but my heart does not
sleep.' "
Yahya related to me from Malik from Ibn Shihab from Urwa ibn az- Zubayr 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, used to pray eleven rakas in the night, making them odd by a single one, and when he had finished he lay down on his right side.
Yahya related to me from Malik from Hisham ibn Urwa from his father that A'isha, umm al-muminin said, "The Messenger of Allah, may Allah bless him and grant him peace, used to pray thirteen rakas in the night and then would pray two rakas when he heard the adhan for the subh prayer."
