Aal-i-Imraan 13

قَدْ كَانَ لَكُمْ ءَايَةٌ فِى فِئَتَيْنِ ٱلْتَقَتَا فِئَةٌ تُقَٰتِلُ فِى سَبِيلِ ٱللَّهِ وَأُخْرَىٰ كَافِرَةٌ يَرَوْنَهُم مِّثْلَيْهِمْ رَأْىَ ٱلْعَيْنِ وَٱللَّهُ يُؤَيِّدُ بِنَصْرِهِۦ مَن يَشَآءُ إِنَّ فِى ذَٰلِكَ لَعِبْرَةً لِّأُو۟لِى ٱلْأَبْصَٰرِ ﴿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 (O Jews) in the two armies that met (in combat i.e. the battle of Badr): One was fighting in the Cause of Allah, and as for the other (they) were disbelievers. They (the believers) saw them (the disbelievers) with their own eyes twice their number (although they were thrice their number). And Allah supports with His Victory whom He pleases. Verily, in this is a lesson for those who understand. (See Verse 8:44). (Tafsir At-Tabari) The Noble Quran
