And Abu Bakr ibn Abi Shaybah and Zuhayr ibn Harb narrated to us; Zuhayr said: Sufyan ibn 'Uyaynah narrated to us, from 'Amr ibn Dinar, from 'Amr ibn Aws, from 'Abdullah ibn 'Amr, may Allah be pleased with them both, who said: The Messenger of Allah, peace and blessings be upon him, said: "Indeed, the most beloved fasting to Allah is the fasting of Dawud, and the most beloved prayer to Allah is the prayer of Dawud, peace be upon him. He used to sleep half of the night, stand (in prayer) for a third of it, and sleep a sixth of it. And he used to fast one day and break his fast the next day."
