Musannaf Ibn Abi Shaybah 36195 — Book of History

It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) said: "The age of Adam was 1,000 years and the age of Dawud (peace be upon him) was 60 years. Adam said: 'O Allah, grant Dawud 40 years out of my life.' So the age of Adam (peace be upon him) was completed to 1,000 years, and the age of Dawud (peace be upon him) was completed to 100 years."
