Sura 4 An-Nisa (The Women), aya 84

1. فَقَاتِلْ فِي سَبِيلِ اللَّهِ لَا تُكَلَّفُ إِلَّا نَفْسَكَ ۚ وَحَرِّضِ الْمُؤْمِنِينَ ۖ عَسَى اللَّهُ أَنْ يَكُفَّ بَأْسَ الَّذِينَ كَفَرُوا ۚ وَاللَّهُ أَشَدُّ بَأْسًا وَأَشَدُّ تَنْكِيلًا

   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.

   4:84
