Al ‘Imrân 3:13
قَدْ كَانَ لَكُمْ آيَةٌ فِي فِئَتَيْنِ الْتَقَتَا ۖ فِئَةٌ تُقَاتِلُ فِي سَبِيلِ اللَّهِ وَأُخْرَىٰ كَافِرَةٌ يَرَوْنَهُم مِّثْلَيْهِمْ رَأْيَ الْعَيْنِ ۚ وَاللَّهُ يُؤَيِّدُ بِنَصْرِهِ مَن يَشَاءُ ۗ إِنَّ فِي ذَٰلِكَ لَعِبْرَةً لِّأُولِي الْأَبْصَارِ ١٣
Qad kana lakum ayatun fee fiatayni iltaqata fiatun tuqatilu fee sabeeli Allahi waokhra kafiratun yarawnahum mithlayhim raya alAAayni waAllahu yuayyidu binasrihi man yashao inna fee thalika laAAibratan liolee alabsari
There has already been a sign for you in the two companies that encountered, one company fighting in the way of God and another unbelieving; they saw them twice the like of them, as the eye sees, but God confirms with His help whom He will. Surely in that is a lesson for men possessed of eyes. (3:13)
