Narrated by Al-Bara' bin 'Azib (may Allah be pleased with him): I saw the Messenger of Allah (peace and blessings be upon him) on the occasion of the Battle of Ahzab (the Trench), carrying earth himself (which was being dug out from the trench). The whiteness of his stomach was hidden by the earth, and he was reciting these verses: "If there were no guidance, how would salvation be attained... How would we pray... How would we give zakat... Now send down tranquility upon us, O Exalted King... Make our feet firm, grant us steadfastness in battle... Without cause, these disbelievers attack us with oppression... When they try to mislead us, we do not listen to their words."
