Surat Al-Anfaal (The Spoils of War) - الأنفال

ٱلْـَٰٔنَ خَفَّفَ ٱللَّهُ عَنكُمْ وَعَلِمَ أَنَّ فِيكُمْ ضَعْفًا فَإِن يَكُن مِّنكُم مِّا۟ئَةٌ صَابِرَةٌ يَغْلِبُوا۟ مِا۟ئَتَيْنِ وَإِن يَكُن مِّنكُمْ أَلْفٌ يَغْلِبُوٓا۟ أَلْفَيْنِ بِإِذْنِ ٱللَّهِ وَٱللَّهُ مَعَ ٱلصَّٰبِرِينَ ﴿٦٦﴾

For the present Allah has made light your burden, and He knows that there is weakness in you; so if there are a hundred patient ones of you they shall overcome two hundred, and if there are a thousand they shall overcome two thousand by Allah's permission, and Allah is with the patient.
