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.
Narrated Narrated Rabi'ah bin Ka'b al-Aslami (RA):
The Prophet (ﷺ) said to me, "Ask." I said, "I ask your company in Paradise." He replied, "Or something else?" I said, "That is it (i.e. that is what I desire)." He said, "Then help me to achieve this for you by devoting yourself often to prostration."
