Nafs - Struggle against Self:
'A human’s soul the (Nafs) is the scene of a struggle of two competing powers. Divine power attracts him towards heavenly spheres, and inspires him to acts of goodness. Satanic power tempts him towards realms of darkness and shame, and invites him to acts of evil. When the divine forces are victorious, a person emerges as a virtuous and blessed being, in the company of righteous. When, however, the satanic forces dominate, the person becomes rebel...lious and vicious and is grouped with infidels, oppressors, wrongdoers and those who are cursed.
Jihad Al-Nafs is the struggle against evil ideas, desires and powers of lust, anger, and insatiable imagination, placing all of them under the dictates of reason and faith in obedience to Allah's commands, and finally, purging all satanic ideas and influences from one’s soul.
This struggle is considered as the greater major struggle as it is much more difficult than fighting in the battlefield, for in the struggle against the self, one has to constantly battle enemies that are hosted inside within his own existence.' (Sheikh Abdul Rahman)
