Surah An-Nisa — Ayah 84 (4:84)
فَقَٰتِلۡ فِي سَبِيلِ ٱللَّهِ لَا تُكَلَّفُ إِلَّا نَفۡسَكَۚ وَحَرِّضِ ٱلۡمُؤۡمِنِينَۖ عَسَى ٱللَّهُ أَن يَكُفَّ بَأۡسَ ٱلَّذِينَ كَفَرُواْۚ وَٱللَّهُ أَشَدُّ بَأۡسٗا وَأَشَدُّ تَنكِيلٗا ٨٤
English translation (Saheeh International)
So fight, [O Muḥammad], in the cause of Allāh; you are not held responsible except for yourself. And encourage the believers [to join you] that perhaps Allāh will restrain the [military] might of those who disbelieve. And Allāh is greater in might and stronger in [exemplary] punishment.1
- - Allāh is able to defeat them in such a way as to deter others from attempting anything similar.
Brief commentary
Fight, O Prophet, in Allah’s path to raise His Word. You will not be questioned about or held accountable for others. You are only responsible to fight yourself and to urge the believers to do so. Perhaps Allah will push back the force of the disbelievers by your fighting. Allah is stronger in force and more severe in punishment.
