Ibn Al-Qayyim reported: Our Sheikh, Ibn Taymiyyah, said, “Jihad against the soul and desires is the foundation of Jihad against the disbelievers and hypocrites. Indeed, it is not possible to strive against them until one strives against himself and his desires; then he can go out against them.”
[Ibn Al-Qayyim, Rawdah Al-Muhibbeen]
قال ابن القيم شيخنا يقول جهاد النفس والهوى أصل جهاد
الكفار والمنافقين فإنه لا يقدر على جهادهم حتى يجاهد نفسه وهواه أولا حتى
يخرج إليهم
روضة المحبين ونزهة المشتاقين
