Surah An-Nisa Verse 84 - English Translation by Ahmed Ali
Surah An-Nisaفَقَٰتِلۡ فِي سَبِيلِ ٱللَّهِ لَا تُكَلَّفُ إِلَّا نَفۡسَكَۚ وَحَرِّضِ ٱلۡمُؤۡمِنِينَۖ عَسَى ٱللَّهُ أَن يَكُفَّ بَأۡسَ ٱلَّذِينَ كَفَرُواْۚ وَٱللَّهُ أَشَدُّ بَأۡسٗا وَأَشَدُّ تَنكِيلٗا
So fight on in the way of God (irrespective of the others). You cannot compel any one except your own self; but urge the believers to fight. It may well be that God will keep back the might of the infidels, for God's might is greater, and severe His punishment
