And when Saul went forth with the soldiers, he said, "Indeed, Allāh will be testing you with a river. So whoever drinks from it is not of me, and whoever does not taste it is indeed of me, excepting one who takes [from it] in the hollow of his hand." But they drank from it, except a [very] few of them. Then when he had crossed it along with those who believed with him, they said, "There is no power for us today against Goliath and his soldiers." But those who were certain that they would meet Allāh said, "How many a small company has overcome a large company by permission of Allāh. And Allāh is with the patient."
