(2:249) So when Saul set out with the gendarmerie (Arab. بِالْجُنُودِ, bil-junūdi), he said, "Allah will test you with a river, whoever drinks from it is not with me, and whoever does not taste from it except one scoop with his hand is with me." They all drank from it, except a few of them. So when he and those who acknowledged with him crossed it, they said, "We have no power today against Goliath and his gendarmerie (Arab. وَجُنُودِهِ, wajunūdihi)!" But the ones who understood that they would meet Allah said, "How many a time has a small group beaten a large group by Allah's leave, and Allah is with the sober!"

(2:250) When they came forth to Goliath and his gendarmerie (Arab. وَجُنُودِهِ, wajunūdihi), they said, "Our Lord grant us sobriety, and make firm our foothold, and grant us victory over the ingrates."
