Muwatta Malik Book 7, Hadith 12
Yahya related to me from Malik from Abdullah ibn Abi Bakr from
his father that Abdullah ibn Qays ibn Makhrama told him that Zayd ibn
Khalid al-Juhani said one night that he was going to observe the
prayer of the Messenger of Allah, may Allah bless him and grant him
peace. He said, "I rested my head on his threshold. The Messenger of
Allah, may Allah bless him and grant him peace, got up and prayed two
long, long, long rakas. Then he prayed two rakas which were slightly
less long than the two before them. Then he prayed two rakas which
were slightly less long than the two before them. Then he prayed two
rakas which were slightly less long than the two before them. Then he
prayed two rakas which were slightly less long than the two before
them. Then he prayed two rakas which were slightly less long than the
two before them. Then he prayed an odd raka, making thirteen rakas in
all."
Yahya related to me from Malik from Makhrama ibn Sulayman from Kurayb, the mawla of Ibn Abbas, that Abdullah ibn Abbas told him that he had spent a night at the house of Maimuna, the wife of the Prophet, may Allah bless him and grant him peace, who was also Ibn Abbas' mother's sister. Ibn Abbas said, "I lay down with my head on the breadth of the cushion, and the Messenger of Allah, may Allah bless him and grant him peace, and his wife lay down with their heads on its length. The Messenger of Allah, may Allah bless him and grant him peace, slept, until, halfway through the night or a little before or after it, he awoke and sat up and wiped the sleep away from his face with his hand. Then he recited the last ten ayats of sura Ali Imran (Sura3). Then he got up and went over to a water-skin which was hanging up and did wudu from it, doing his wudu thoroughly, and then he stood in prayer."
Ibn Abbas continued, "I stood up and did the same and then went and stood by his side. The Messenger of Allah, may Allah bless him and grant him peace, put his right hand on my head and took my right ear and tweaked it. He prayed two rakas, then two rakas, then two rakas, then two rakas, then two rakas, then two rakas, and then prayed an odd raka. Then he lay down until the muadhdhin came to him, and then prayed two quick rakas, and went out and prayed subh ."
Yahya related to me from Malik from Nafi and Abdullah ibn Umar that a man asked the Messenger of Allah, may Allah bless him and grant him peace, about night prayers. The Messenger of Allah, may Allah bless him and grant him peace, said, "Night prayers are two by two, and when you are afraid that dawn is approaching, pray one raka to make what you have prayed odd."
