Musannaf Ibn Abi Shaybah 3024 — How the tashahhud in prayer is recited

Ibrahim says: Alqamah was teaching a Bedouin the words of the tashahhud, saying: Peace be upon you, O Prophet, and may the mercy of Allah and His blessings descend. And the Bedouin was saying: Peace be upon you, O Prophet, and the mercy of Allah, and the blessings of Allah, and the forgiveness of Allah. The Bedouin kept repeating it this way. At this, Alqamah said: This is how we were taught.
