The Book of Prayer
وَعَنْ اِبْنِ عُمَرَ -رَضِيَ اَللَّهُ عَنْهُمَا- قَالَ : { حَفِظْتُ مِنْ اَلنَّبِيِّ - صلى الله عليه وسلم -عَشْرَ رَكَعَاتٍ : رَكْعَتَيْنِ قَبْلَ اَلظُّهْرِ , وَرَكْعَتَيْنِ بَعْدَهَا , وَرَكْعَتَيْنِ بَعْدَ اَلْمَغْرِبِ فِي بَيْتِهِ , وَرَكْعَتَيْنِ بَعْدَ اَلْعِشَاءِ فِي بَيْتِهِ , وَرَكْعَتَيْنِ قَبْلَ اَلصُّبْحِ } مُتَّفَقٌ عَلَيْهِ . [1]
Narrated Ibn 'Umar (RA): I memorized from the Prophet (ﷺ) ten (voluntary) Rak'at - two Rak'at before the Zuhr prayer and two after it; two Rak'at after Maghrib prayer in his house, and two Rak'at after 'Isha' prayer in his house, and two Rak'at before the Fajr prayer. [Agreed upon].
