84فَقَـٰتِلْ فِى سَبِيلِ ٱللَّهِ لَا تُكَلَّفُ إِلَّا نَفْسَكَ ۚ وَحَرِّضِ ٱلْمُؤْمِنِينَ ۖ عَسَى ٱللَّهُ أَن يَكُفَّ بَأْسَ ٱلَّذِينَ كَفَرُوا۟ ۚ وَٱللَّهُ أَشَدُّ بَأْسًا وَأَشَدُّ تَنكِيلًا
85مَّن يَشْفَعْ شَفَـٰعَةً حَسَنَةً يَكُن لَّهُۥ نَصِيبٌ مِّنْهَا ۖ وَمَن يَشْفَعْ شَفَـٰعَةً سَيِّئَةً يَكُن لَّهُۥ كِفْلٌ مِّنْهَا ۗ وَكَانَ ٱللَّهُ عَلَىٰ كُلِّ شَىْءٍ مُّقِيتًا
[84-85] O Prophet, fight in the way of Allah: you are accountable for none but your own person; you should, however, urge on the Believers to fight: it may be that Allah will soon break the strength of the disbelievers, for Allah is the strongest in might and His punishment is most severe. Whoever pleads a good cause, will get a share from it, and whoever pleads an evil cause also shall get a share from it;113 for Allah keeps strict watch over everything.
113Different people behave differently and with different results. Some urge on others to exert themselves for the cause of Allah and to exalt His Word and they get its reward. There are others who spread misunderstandings among the people about Allah's cause, discourage the Muslims and try to dissuade them from exalting the Word of Allah and thus incur punishment.
