Musannaf Ibn Abi Shaybah 39582 — The Battle of the Trench

It is narrated from Sayyiduna al-Bara (may Allah be pleased with him): I saw the Messenger of Allah (peace and blessings be upon him) carrying soil on the day of the Trench, until the soil had covered the blessed hair of his (peace and blessings be upon him) chest. And he (peace and blessings be upon him) was reciting the rajaz of Abdullah bin Rawahah and saying: "O Allah, were it not for You we would not have been guided, nor would we have given charity, nor would we have prayed." "So send down tranquillity upon us, and make our feet firm if we meet (the enemy)." "Indeed, these people have transgressed against us, and if they want tribulation, we will refuse."
