So, when Tālūt set out along with the troops, he said: “Allah is going to test you by a river, so, whoever drinks from it is not my man, and whoever does not taste it is surely a man of mine, except the one who scoops a little with his hand.” Then they drank from it, except a few of them. So, when it (the river) was crossed by him and by those who believed with him, they said: “There is no strength with us today against Jālūt and his troops.” Said those who believed in their having to meet Allah: “How many small groups have overcome large groups by the will of Allah. Allah is with those who remain patient.”
And when they faced Jālūt and his troops, they said: “Our Lord, pour out endurance on us, make firm our feet and help us against the disbelieving people.”
So, they defeated them by the will of Allah, and Dāwūd (David) killed Jālūt, and Allah gave him the kingdom and the wisdom and taught him what He willed. Had Allah not been pushing back some people by means of others, the earth would have been spoiled. But Allah is All-Gracious to all the worlds.
