Al Anfal Ayah 66

ٱلْـَٔـٰنَ خَفَّفَ ٱللَّهُ عَنكُمْ وَعَلِمَ أَنَّ فِيكُمْ ضَعْفًا‌ۚ فَإِن يَكُن مِّنكُم مِّاْئَةٌ صَابِرَةٌ يَغْلِبُواْ مِاْئَتَيْنِ‌ۚ وَإِن يَكُن مِّنكُمْ أَلْفٌ يَغْلِبُوٓاْ أَلْفَيْنِ بِإِذْنِ ٱللَّهِ‌ۗ وَٱللَّهُ مَعَ ٱلصَّـٰبِرِينَ ٦٦ Now Allah has lightened your burden, for He knows that there is weakness in you. So if there are a hundred steadfast among you, they will overcome two hundred. And if there be one thousand, they will overcome two thousand, by Allah’s Will. And Allah is with the steadfast.
