Musannaf Ibn Abi Shaybah 31572 — What is mentioned from various people

Ibrahim said: There was a man among us named Hammam bin al-Harith. He would not sleep except for a short while, sitting in the mosque in a state of prayer, and he used to supplicate in this way: "O Allah, cure me of sleep with only a little of it, and grant me wakefulness in obedience to You."
