The Struggle for Allah-azwj, either Physically or within oneself
قُلْ إِنْ كَانَ آبَاؤُكُمْ وَأَبْنَاؤُكُمْ وَإِخْوَانُكُمْ وَأَزْوَاجُكُمْ وَعَشِيرَتُكُمْ وَأَمْوَالٌ اقْتَرَفْتُمُوهَا وَتِجَارَةٌ تَخْشَوْنَ كَسَادَهَا وَمَسَاكِنُ تَرْضَوْنَهَا أَحَبَّ إِلَيْكُمْ مِنَ اللَّهِ وَرَسُولِهِ وَجِهَادٍ فِي سَبِيلِهِ فَتَرَبَّصُوا حَتَّىٰ يَأْتِيَ اللَّهُ بِأَمْرِهِ ۗ وَاللَّهُ لَا يَهْدِي الْقَوْمَ الْفَاسِقِينَ {24}
Say: ‘If it was your fathers, and your sons, and your brethren, and your wives, and your clan, and your acquired wealth, and the slowdown in trade you fear, and the dwellings you are pleased with are more beloved to you than Allah and His Rasool and ‘جِهَادٍ’ the Jihad in the Way of Allah, then wait until Allah Comes with his Command; and Allah does not Guide the mischief-making people’ [9:24]
عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ النَّوْفَلِيِّ عَنِ السَّكُونِيِّ عَنْ أَبِي عَبْدِ اللَّهِ ع أَنَّ النَّبِيَّ ص بَعَثَ بِسَرِيَّةٍ فَلَمَّا رَجَعُوا قَالَ مَرْحَباً بِقَوْمٍ قَضَوُا الْجِهَادَ الْأَصْغَرَ وَ بَقِيَ الْجِهَادُ الْأَكْبَرُ قِيلَ يَا رَسُولَ اللَّهِ ص وَ مَا الْجِهَادُ الْأَكْبَرُ قَالَ جِهَادُ النَّفْسِ
Ali ibn Ibrahim has narrated from his father, who from al-Nawfaliy from al-Sakuniy who has said the following:
Abu Abd Allah-asws has said that the Messenger of Allah-saww once mobilised a group of people against the enemy. When they returned back, he-saww said: ‘I welcome a people who have just come back after completion of the minor Jihad and who yet have to complete the major Jihad.’ Someone then asked, ‘What is the major Jihad, O Messenger of Allah-saww?’ He-saww replied, ‘It is Jihad against the desires of one’s own soul which encourages one to disobey Allah-azwj.[1]
