فَلَمَّا فَصَلَ طَالُوتُ بِالْجُنُودِ قَالَ إِنَّ اللَّهَ مُبْتَلِيكُم بِنَهَرٍ فَمَن شَرِبَ مِنْهُ فَلَيْسَ مِنِّي وَمَن لَّمْ يَطْعَمْهُ فَإِنَّهُ مِنِّي إِلَّا مَنِ اغْتَرَفَ غُرْفَةً بِيَدِهِ فَشَرِبُوا مِنْهُ إِلَّا قَلِيلًا مِّنْهُمْ فَلَمَّا جَاوَزَهُ هُوَ وَالَّذِينَ آمَنُوا مَعَهُ قَالُوا لَا طَاقَةَ لَنَا الْيَوْمَ بِجَالُوتَ وَجُنُودِهِ قَالَ الَّذِينَ يَظُنُّونَ أَنَّهُم مُّلَاقُو اللَّهِ كَم مِّن فِئَةٍ قَلِيلَةٍ غَلَبَتْ فِئَةً كَثِيرَةً بِإِذْنِ اللَّهِ وَاللَّهُ مَعَ الصَّابِرِينَ ٢٤٩

فِئَةٍ fi-atin · a company

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." (Surah Al-Baqarah, 2:249)

قَدْ كَانَ لَكُمْ آيَةٌ فِي فِئَتَيْنِ الْتَقَتَا فِئَةٌ تُقَاتِلُ فِي سَبِيلِ اللَّهِ وَأُخْرَىٰ كَافِرَةٌ يَرَوْنَهُم مِّثْلَيْهِمْ رَأْيَ الْعَيْنِ وَاللَّهُ يُؤَيِّدُ بِنَصْرِهِ مَن يَشَاءُ إِنَّ فِي ذَٰلِكَ لَعِبْرَةً لِّأُولِي الْأَبْصَارِ ١٣

فِئَتَيْنِ fi-atayni · (the) two hosts

Already there has been for you a sign in the two armies which met [in combat at Badr] - one fighting in the cause of Allāh and another of disbelievers. They saw them [to be] twice their [own] number by [their] eyesight. But Allāh supports with His victory whom He wills. Indeed in that is a lesson for those of vision. (Surah Ali 'Imran, 3:13)

إِن تَسْتَفْتِحُوا فَقَدْ جَاءَكُمُ الْفَتْحُ وَإِن تَنتَهُوا فَهُوَ خَيْرٌ لَّكُمْ وَإِن تَعُودُوا نَعُدْ وَلَن تُغْنِيَ عَنكُمْ فِئَتُكُمْ شَيْئًا وَلَوْ كَثُرَتْ وَأَنَّ اللَّهَ مَعَ الْمُؤْمِنِينَ ١٩

فِئَتُكُمْ fi-atukum · your forces

If you [disbelievers] seek the decision [i.e., victory] - the decision [i.e., defeat] has come to you. And if you desist [from hostilities], it is best for you; but if you return [to war], We will return, and never will you be availed by your [large] company at all, even if it should increase; and [that is] because Allāh is with the believers. (Surah Al-Anfal, 8:19)
