Musnad Ahmad 4044

It was narrated that Tariq bin Shihab said: I heard Ibn Mas'ood say: I was present with al-Miqdad bin al-Aswad -someone else said - during an incident which, if it were to happen to me, it would be dearer to me than anything else. He came to The Messenger of Allah (ﷺ) when he was praying against the mushrikeen and said. By Allah, O Messenger of Allah, we will not say as the people of Moosa said (to Moosa), "So go you and your Lord and fight you two, we are sitting right here" (al-Ma’idah 5:24); rather we will fight on your right and on your left, in front of you and behind you. And I saw the face of the Messenger of Allah (ﷺ) brighten and he was pleased with that.
