I remember ten Rakat of Nawafil from the Prophet, two Rakat before the Zuhr prayer and two after it; two Rakat after Maghrib prayer in his house, and two Rakat after 'Isha' prayer in his house, and two Rakat before the Fajr prayer and at that time nobody would enter the house of the Prophet. Hafsa told me that the Prophet ﷺ used to offer two Rakat after the call maker had made the Adhan and the day had dawned.  

حَفِظْتُ مِنَ النَّبِيِّ ﷺ عَشْرَ رَكَعَاتٍ رَكْعَتَيْنِ قَبْلَ الظُّهْرِ وَرَكْعَتَيْنِ بَعْدَهَا وَرَكْعَتَيْنِ بَعْدَ الْمَغْرِبِ فِي بَيْتِهِ وَرَكْعَتَيْنِ بَعْدَ الْعِشَاءِ فِي بَيْتِهِ وَرَكْعَتَيْنِ قَبْلَ صَلاَةِ الصُّبْحِ وَكَانَتْ سَاعَةً لاَ يُدْخَلُ عَلَى النَّبِيِّ ﷺ فِيهَا حَدَّثَتْنِي حَفْصَةُ أَنَّهُ كَانَ إِذَا أَذَّنَ الْمُؤَذِّنُ وَطَلَعَ الْفَجْرُ صَلَّى رَكْعَتَيْنِ  

The Prophet ﷺ never missed four rakʿat before the Zuhr prayer and two rakʿat before the Fajr prayer.  

أَنَّ النَّبِيَّ ﷺ كَانَ لاَ يَدَعُ أَرْبَعًا قَبْلَ الظُّهْرِ وَرَكْعَتَيْنِ قَبْلَ الْغَدَاةِ
