8 : 66
ٱلۡـَٰٔنَ خَفَّفَ ٱللَّهُ عَنكُمۡ وَعَلِمَ أَنَّ فِيكُمۡ ضَعۡفٗاۚ فَإِن يَكُن مِّنكُم مِّاْئَةٞ صَابِرَةٞ يَغۡلِبُواْ مِاْئَتَيۡنِۚ وَإِن يَكُن مِّنكُمۡ أَلۡفٞ يَغۡلِبُوٓاْ أَلۡفَيۡنِ بِإِذۡنِ ٱللَّهِۗ وَٱللَّهُ مَعَ ٱلصَّٰبِرِينَ
Now Allah has lightened your burden, for He knew that there is weakness in you. So if there are a hundred steadfast men among you, they will overcome two hundred; and if there are a thousand, they will overcome two thousand, by Allah’s permission. And Allah is with those who are steadfast.
