4 : 84
فَقَٰتِلۡ فِي سَبِيلِ ٱللَّهِ لَا تُكَلَّفُ إِلَّا نَفۡسَكَۚ وَحَرِّضِ ٱلۡمُؤۡمِنِينَۖ عَسَى ٱللَّهُ أَن يَكُفَّ بَأۡسَ ٱلَّذِينَ كَفَرُواْۚ وَٱللَّهُ أَشَدُّ بَأۡسٗا وَأَشَدُّ تَنكِيلٗا
So fight in the way of Allah [O Prophet]; you are accountable only for yourself. But urge the believers [to fight]; perhaps Allah will restrain the might of the disbelievers, for Allah is strongest in might and severe in punishment.
