Musannaf Ibn Abi Shaybah 3380 — Whether the later Isha is hastened

Sayyiduna Ibn Abbas (may Allah be pleased with them both) said: One night the Messenger of Allah (peace and blessings be upon him) delayed the Isha prayer. When he came out, drops of water were dripping from his blessed head, and he said: "Were it not that I feared hardship for my Ummah, I would make this the time for this prayer."
