We went out with the Prophet, and when we came to `Usfan he stayed there some nights. The people said, "We are serving no purpose here, our children have been left and we are not sure of their safety," and when the Prophet heard of that he said, "I swear by Him in whose hand my soul is that there is no ravine or mountain road in Medina which does not have two angels guarding it till you return." He then gave the order to set out, and we did so and came to Medina. Then, by Him in whose name oaths are sworn, we had not unloaded our beasts after entering Medina before the B. 'Abdallah b. Ghatafan raided us, but nothing had roused them to do so before that. Muslim transmitted it.
