فَلَمَّا فَصَلَ طَالُوتُ بِٱلۡجُنُودِ قَالَ إِنَّ ٱللَّهَ مُبۡتَلِيكُم بِنَهَرٖ فَمَن شَرِبَ مِنۡهُ فَلَيۡسَ مِنِّي وَمَن لَّمۡ يَطۡعَمۡهُ فَإِنَّهُۥ مِنِّيٓ إِلَّا مَنِ ٱغۡتَرَفَ غُرۡفَةَۢ بِيَدِهِۦۚ فَشَرِبُواْ مِنۡهُ إِلَّا قَلِيلٗا مِّنۡهُمۡۚ فَلَمَّا جَاوَزَهُۥ هُوَ وَٱلَّذِينَ ءَامَنُواْ مَعَهُۥ قَالُواْ لَا طَاقَةَ لَنَا ٱلۡيَوۡمَ بِجَالُوتَ وَجُنُودِهِۦۚ قَالَ ٱلَّذِينَ يَظُنُّونَ أَنَّهُم مُّلَٰقُواْ ٱللَّهِ كَم مِّن فِئَةٖ قَلِيلَةٍ غَلَبَتۡ فِئَةٗ كَثِيرَةَۢ بِإِذۡنِ ٱللَّهِۗ وَٱللَّهُ مَعَ ٱلصَّٰبِرِينَ

When Talut set forth with the armies, he said: "Allah will test you at the stream: if any drinks of its water, He goes not with my army: Only those who taste not of it go with me: A mere sip out of the hand is excused." but they all drank of it, except a few. When they crossed the river,- He and the faithful ones with him,- they said: "This day We cannot cope with Goliath and his forces." but those who were convinced that they must meet Allah, said: "How oft, by Allah's will, Hath a small force vanquished a big one? Allah is with those who steadfastly persevere."
