8 : 43
إِذۡ يُرِيكَهُمُ ٱللَّهُ فِي مَنَامِكَ قَلِيلٗاۖ وَلَوۡ أَرَىٰكَهُمۡ كَثِيرٗا لَّفَشِلۡتُمۡ وَلَتَنَٰزَعۡتُمۡ فِي ٱلۡأَمۡرِ وَلَٰكِنَّ ٱللَّهَ سَلَّمَۚ إِنَّهُۥ عَلِيمُۢ بِذَاتِ ٱلصُّدُورِ
[Remember] when Allah showed them to you in your dream as few in number; if He had shown them to you as many, you [believers] would have lost courage and disputed in the matter. But Allah spared you [of that], for He is All-Knowing of what is in the hearts.
