فَقاتِل في سَبيلِ اللَّهِ لا تُكَلَّفُ إِلّا نَفسَكَ ۚ وَحَرِّضِ المُؤمِنينَ ۖ عَسَى اللَّهُ أَن يَكُفَّ بَأسَ الَّذينَ كَفَروا ۚ وَاللَّهُ أَشَدُّ بَأسًا وَأَشَدُّ تَنكيلًا

So fight, [O Muhammad], in the cause of Allah; you are not held responsible except for yourself. And encourage the believers [to join you] that perhaps Allah will restrain the [military] might of those who disbelieve. And Allah is greater in might and stronger in [exemplary] punishment.
