Quran 4:84 An-Nisa, ayah 84 of 176

فَقَـٰتِلْ فِى سَبِيلِ ٱللَّهِ لَا تُكَلَّفُ إِلَّا نَفْسَكَ ۚ وَحَرِّضِ ٱلْمُؤْمِنِينَ ۖ عَسَى ٱللَّهُ أَن يَكُفَّ بَأْسَ ٱلَّذِينَ كَفَرُوا۟ ۚ وَٱللَّهُ أَشَدُّ بَأْسًا وَأَشَدُّ تَنكِيلًا ۝٨٤

4:84 So fight (O Muhammad) in the way of Allah Thou art not taxed (with the responsibility for anyone) except thyself - and urge on the believers. Peradventure Allah will restrain the might of those who disbelieve. Allah is stronger in might and stronger in inflicting punishment.
