Musannaf Ibn Abi Shaybah 8872 — Sending blessings upon the Prophet

Al-Hasan said: The people said: "O Messenger of Allah! We have learned the way of sending salam upon you; now teach us the way of sending salah (blessings) as well." He said: "Say: 'O Allah! Place Your mercies and Your blessings upon the family of Muhammad (peace and blessings be upon him), as You placed them upon the family of Ibrahim. You are Praiseworthy, Glorious.'"
