I spent the night at the home of my aunt Maymunah. The Messenger of Allah ﷺ talked with his family for a while, then went to sleep. When the last third of the night came, he sat up, looked toward the sky, and recited, "Indeed, in the creation of the heavens and the earth and the alternation of the night and the day are signs for those of understanding" [Aal Imran 3:190].Then he got up, performed ablution, cleaned his teeth with a siwak, and prayed eleven units of prayer. Then Bilal called the adhan, so he prayed two units, then went out and led the dawn prayer.
بت عند خالتي ميمونة، فتحدث رسول الله ﷺ مع أهله ساعة ثم رقد، فلما كان ثلث الليل الآخر قعد، فنظر إلى السماء فقال: {إن في خلق السموات والأرض واختلاف اليل والنهار لآيت لأولي الألباب} ثم قام فتوضأ واستن، فصلى إحدى عشرة ركعة، ثم أذن بلال فصلى ركعتين، ثم خرج فصلى الصبح.
Bukhari related it in the tafsir (4569) and Muslim in the prayer of the traveler (763:190), both through Saeed bin Abu Maryam, who said, Muhammad bin Jafar informed us, who said, Sharik bin Abdullah bin Abu Nimr informed me, from Kurayb, from Ibn Abbas, and he narrated it. The wording given is Bukhari's, for Muslim did not present his own wording with this chain, but instead referred to the wording of the hadith before it.
