اِعْلَمْ أَنَّهُ إِنَّمَا كَانَ جِهَادُ النَّفْسِ أَكْبَرَ مِنْ جِهَادِ الأَعْدَاءِ
Know that the struggle against one's self is indeed greater than the struggle against enemies.
لِأَنَّ النَّفْسَ مَحْبُوبَةٌ
Because the self is beloved.
وَمَا تَدْعُو إِلَيْهِ مَحْبُوبٌ
And what it calls to is beloved.
لِأَنَّهَا لَا تَدْعُو إِلَّا إِلَى مَا تَشْتَهِي
Because it only calls to what it desires.
وَمُوَافَقَةُ الْمَحْبُوبِ فِي الْمَكْرُوهِ مَحْبُوبَةٌ فَكَيْفَ إِذَا دَعَا إِلَى مَحْبُوبٍ
And agreeing with the beloved even in what is disliked is beloved, so how much more when it calls to something beloved?
فَ إِذْ عَكَسْتَ الْحَالَ
So when you reverse the state,
وَخُولِفَ الْمَحْبُوبُ فِيمَا يَدْعُو إِلَيْهِ مِنَ الْمَحْبُوبِ
And the beloved is opposed in what it calls to of beloved things,
اشْتَدَّ الْجِهَادُ وَصَعُبَ الأَمْرُ بِخِلَافِ جِهَادِ الْكُفَّارِ
The struggle becomes intense and the matter becomes difficult, unlike the struggle against the disbelievers.
فَإِنَّ الطِّبَاعَ تَحْمِلُ عَلَى خُصُومَةِ الأَعْدَاءِ
For nature inclines towards opposing enemies.
