The Book on Salat (Prayer) — Hadith #435
حَدَّثَنَا الْحَسَنُ بْنُ عَلِيٍّ، حَدَّثَنَا عَبْدُ الرَّزَّاقِ، أَخْبَرَنَا مَعْمَرٌ، عَنِ الزُّهْرِيِّ، عَنْ سَالِمٍ، عَنِ ابْنِ عُمَرَ، عَنِ النَّبِيِّ صلى الله عليه وسلم مِثْلَهُ . قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ .
"I memorized ten Rak'ah from Allah's Messenger (S) which he would pray in a night and a day: Two Rak'ah before Az-Zuhr, two after it; two Rak'ah after Al-Maghrib and two Rak'ah after the latter Isha." He said: "And Hafsah narrated to me that he (S) would pray two Rak'ah before Al-Fajr."
