وَٱلَّذِينَ جَٰهَدُوا۟ فِينَا لَنَهْدِيَنَّهُمْ سُبُلَنَا ۚ وَإِنَّ ٱللَّهَ لَمَعَ ٱلْمُحْسِنِينَ ﴿٦٩﴾
As for those who strive in Us, We surely guide them to Our paths, and lo! Allah is with the good.
What is jihad?
Short answer
Jihad means striving or struggling. It covers any effort for good: struggling against one's own bad habits, striving to be honest, working hard to support a family, speaking the truth to a tyrant and, as a last resort, defending people by arms under strict rules.
The fuller answer
Most of the uses of the word in the Quran and hadith are about struggle in ordinary life: for knowledge, patience and good character. The Prophet ﷺ called the best jihad 'a word of truth before an unjust ruler', and described the one who strives against his own self for God's sake as a true fighter. A narration widely repeated about a 'greater jihad' against the self has a weak chain, but its meaning is supported by many authentic texts.
Armed struggle (qital) is a part of jihad and is permitted only in defence against aggression and injustice, with the approval of a legitimate authority, and with firm limits on the conduct of war. A person or group has no right in Islam to declare jihad by themselves, and attacks on civilians are never jihad.
From the Quran
وَجَٰهِدُوا۟ فِى ٱللَّهِ حَقَّ جِهَادِهِۦ ۚ هُوَ ٱجْتَبَىٰكُمْ وَمَا جَعَلَ عَلَيْكُمْ فِى ٱلدِّينِ مِنْ حَرَجٍۢ ۚ مِّلَّةَ أَبِيكُمْ إِبْرَٰهِيمَ ۚ هُوَ سَمَّىٰكُمُ ٱلْمُسْلِمِينَ مِن قَبْلُ وَفِى هَٰذَا لِيَكُونَ ٱلرَّسُولُ شَهِيدًا عَلَيْكُمْ وَتَكُونُوا۟ شُهَدَآءَ عَلَى ٱلنَّاسِ ۚ فَأَقِيمُوا۟ ٱلصَّلَوٰةَ وَءَاتُوا۟ ٱلزَّكَوٰةَ وَٱعْتَصِمُوا۟ بِٱللَّهِ هُوَ مَوْلَىٰكُمْ ۖ فَنِعْمَ ٱلْمَوْلَىٰ وَنِعْمَ ٱلنَّصِيرُ ﴿٧٨﴾
And strive for Allah with the endeavour which is His right. He hath chosen you and hath not laid upon you in religion any hardship; the faith of your father Abraham (is yours). He hath named you Muslims of old time and in this (Scripture), that the messenger may be a witness against you, and that ye may be witnesses against mankind. So establish worship, pay the poor-due, and hold fast to Allah. He is your Protecting friend. A blessed Patron and a blessed Helper!
وَقَٰتِلُوا۟ فِى سَبِيلِ ٱللَّهِ ٱلَّذِينَ يُقَٰتِلُونَكُمْ وَلَا تَعْتَدُوٓا۟ ۚ إِنَّ ٱللَّهَ لَا يُحِبُّ ٱلْمُعْتَدِينَ ﴿١٩٠﴾
Fight in the way of Allah against those who fight against you, but begin not hostilities. Lo! Allah loveth not aggressors.
