Musnad Ahmad Hadith 18684

It is narrated from Bara’ (may Allah be pleased with him) that I saw the Noble Prophet (ﷺ) on the occasion of the digging of the trench, that he (peace be upon him) was carrying earth along with the people, until the earth covered the skin of his stomach, and he (peace be upon him) was reciting these verses of (Abdullah bin Rawaha, may Allah be pleased with him): O Allah, if You were not (with us), we would not have found guidance, nor given charity, nor performed prayer. So send down tranquility upon us, and make us steadfast when we meet the enemy. These people have rebelled against us, and when they intend to cause mischief, we refuse (to comply). Upon this last sentence, the Noble Prophet (ﷺ) would raise his voice.
