Sura al-Baqara 2:249

فَلَمَّا فَصَلَ طَالُوتُ بِٱلْجُنُودِ قَالَ إِنَّ ٱللَّـهَ مُبْتَلِيكُم بِنَهَرٍ فَمَن شَرِبَ مِنْهُ فَلَيْسَ مِنِّى وَمَن لَّمْ يَطْعَمْهُ فَإِنَّهُۥ مِنِّىٓ إِلَّا مَنِ ٱغْتَرَفَ غُرْفَةًۢ بِيَدِهِۦ فَشَرِبُوا۟ مِنْهُ إِلَّا قَلِيلًا مِّنْهُمْ فَلَمَّا جَاوَزَهُۥ هُوَ وَٱلَّذِينَ ءَامَنُوا۟ مَعَهُۥ قَالُوا۟ لَا طَاقَةَ لَنَا ٱلْيَوْمَ بِجَالُوتَ وَجُنُودِهِۦ قَالَ ٱلَّذِينَ يَظُنُّونَ أَنَّهُم مُّلَٰقُوا۟ ٱللَّـهِ كَم مِّن فِئَةٍ قَلِيلَةٍ غَلَبَتْ فِئَةً كَثِيرَةًۢ بِإِذْنِ ٱللَّـهِ وَٱللَّـهُ 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."

Sura al-Muʾminūn 23:106

قَالُوا۟ رَبَّنَا غَلَبَتْ عَلَيْنَا شِقْوَتُنَا وَكُنَّا قَوْمًا ضَآلِّينَ

qālū rabbanā ghalabat ʿalaynā shiqwatunā wa-kunnā qawman ḍāllīna

They will say: "our Lord! Our misfortune overwhelmed us, and we became a people astray!
