Sahih Bukhari Book: 14, Hadith: 994

حَدَّثَنَا أَبُو الْيَمَانِ، قَالَ أَخْبَرَنَا شُعَيْبٌ، عَنِ الزُّهْرِيِّ، عَنْ عُرْوَةَ، أَنَّ عَائِشَةَ، أَخْبَرَتْهُ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم كَانَ يُصَلِّي إِحْدَى عَشْرَةَ رَكْعَةً، كَانَتْ تِلْكَ صَلاَتَهُ ـ تَعْنِي بِاللَّيْلِ ـ فَيَسْجُدُ السَّجْدَةَ مِنْ ذَلِكَ قَدْرَ مَا يَقْرَأُ أَحَدُكُمْ خَمْسِينَ آيَةً قَبْلَ أَنْ يَرْفَعَ رَأْسَهُ، وَيَرْكَعُ رَكْعَتَيْنِ قَبْلَ صَلاَةِ الْفَجْرِ، ثُمَّ يَضْطَجِعُ عَلَى شِقِّهِ الأَيْمَنِ حَتَّى يَأْتِيَهُ الْمُؤَذِّنُ لِلصَّلاَةِ‏.‏ Narrated `Aisha: Allah’s Apostle used to pray eleven rak`at at night and that was his night prayer and each of his prostrations lasted for a period enough for one of you to recite fifty verses before Allah’s Apostle raised his head. He also used to pray two rak`at (Sunna) before the (compulsory) Fajr prayer and then lie down on his right side till the Mu’adh-dhin came to him for the prayer.
