Sura Āl-ʿImrān 3:13

قَدْ كَانَ لَكُمْ ءَايَةٌ فِى فِئَتَيْنِ ٱلْتَقَتَا فِئَةٌ تُقَٰتِلُ فِى سَبِيلِ ٱللَّـهِ وَأُخْرَىٰ كَافِرَةٌ يَرَوْنَهُم مِّثْلَيْهِمْ رَأْىَ ٱلْعَيْنِ وَٱللَّـهُ يُؤَيِّدُ بِنَصْرِهِۦ مَن يَشَآءُ إِنَّ فِى ذَٰلِكَ لَعِبْرَةً لِّأُو۟لِى ٱلْأَبْصَٰرِ

qad kāna la-kum āyatun fī fiʾatayni ltaqatā fiʾatun tuqātilu fī sabīli allāhi wa-ukhrā kāfiratun yarawnahum mithlayhim raʾya l-ʿayni wallāhu yuʾayyidu binaṣrihi man yashāʾu inna fī dhālika la-ʿibratan li-lūlī l-abṣāri

"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."
