"I memorized ten Rak'ah from Messenger of Allah (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."
عَنْ رَسُولِ اللَّهِ ﷺ عَشْرَ رَكَعَاتٍ كَانَ يُصَلِّيهَا بِاللَّيْلِ وَالنَّهَارِ رَكْعَتَيْنِ قَبْلَ الظُّهْرِ وَرَكْعَتَيْنِ بَعْدَهَا وَرَكْعَتَيْنِ بَعْدَ الْمَغْرِبِ وَرَكْعَتَيْنِ بَعْدَ الْعِشَاءِ الآخِرَةِ قَالَ وَحَدَّثَتْنِي حَفْصَةُ أَنَّهُ كَانَ يُصَلِّي قَبْلَ الْفَجْرِ رَكْعَتَيْنِ هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ
