It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that I have memorized ten rak‘ahs from the Prophet (peace and blessings be upon him) which he used to perform regularly: two rak‘ahs before the Zuhr prayer and two after it, two rak‘ahs after Maghrib, two rak‘ahs after ‘Isha, and two rak‘ahs before the Fajr prayer.
