Musannaf Ibn Abi Shaybah

Hazrat Ibn Abbas (may Allah be pleased with both of them) narrates that the Messenger of Allah (peace and blessings be upon him) once delayed the ‘Isha prayer one night. When he arrived, drops of water were dripping from his blessed head. He said, “If I did not fear hardship for my Ummah, I would have fixed this time for this prayer.”
