قَدۡ كَانَ لَكُمۡ ءَايَةٞ فِي فِئَتَيۡنِ ٱلۡتَقَتَاۖ فِئَةٞ تُقَٰتِلُ فِي سَبِيلِ ٱللَّهِ وَأُخۡرَىٰ كَافِرَةٞ يَرَوۡنَهُم مِّثۡلَيۡهِمۡ رَأۡيَ ٱلۡعَيۡنِۚ وَٱللَّهُ يُؤَيِّدُ بِنَصۡرِهِۦ مَن يَشَآءُۚ إِنَّ فِي ذَٰلِكَ لَعِبۡرَةٗ لِّأُوْلِي ٱلۡأَبۡصَٰرِ

Qad kaana lakum Aayatun fee fi'atainil taqataa fi'atun tuqaatilu fee sabeelil laahi wa ukhraa kaafiratuny yarawnahum mislaihim ra' yal 'ayn; wallaahu yu'ayyidu bi nasrihee mai yashaaa'; innaa fee zaalika la 'ibratal li ulil absaar

"There has already been for you a Sign in the two armies that met (in combat): One was fighting in the cause of Allah, the other resisting Allah; these saw with their own eyes Twice their number. But Allah doth support with His aid whom He pleaseth. In this is a warning for such as have eyes to see."

— Aali Imran (آلِ عِمْرَان), 3:13
