Musannaf Ibn Abi Shaybah 8716 — The excellence of the night prayer

Sayyiduna Ibn Abbas (may Allah be pleased with them both) said: Once I spent the night with my maternal aunt, the Mother of the Believers Sayyidah Maymunah (may Allah be pleased with her). That night the Messenger of Allah (peace and blessings be upon him) was also at her place. During the night I saw him get up, and he prayed eleven or thirteen rak'ahs.
