Musannaf Ibn Abi Shaybah 6101 — What is liked of voluntary prayer

Sayyiduna Ibn Umar (may Allah be pleased with them both) said: I preserved from the Messenger of Allah (peace and blessings be upon him) eight rak'ahs: two before Zuhr, two after Zuhr, two after Maghrib and two after Isha. Sayyidah Hafsah (may Allah be pleased with her) also told me of the two rak'ahs before Fajr.
