wa'lladhina jahadu feena
but those who strive for Us.
~ The Chapter of Spider, The Final Testament 29:69
Imam Jafar as Sadiq, may God hallow his spirit, said: The spiritual struggle (jihad) is sincere neediness (to God) and that is the detachment (infisal) of the servant from his soul, and his attachment (ittisal) to his Lord.
[Detachment (infisal) and attachment (ittisal). Thus the nafi and ithbat respectively, of the shahadah constitute mujahadah.]
The spiritual struggle frees the slave from all that he is attached to. The spiritual struggle is the generous expending of one's spirit (Badhl ar-Ruh) for the the satisfaction of (God) the Truth.
[Badhl al-Ruh. Since spirit (ruh) is the divine breath of life breathed into man at his creation, badhl al-ruh means to expend the whole of life appropriately, at all levels, in satisfying the One who breathes through and in all creatures. Safa too has its service to God, its khidmah.]
He also said: Whoever strives with his soul for his soul attains the munificence of his Lord; while he who strives with his soul for his Lord attains to his Lord.
[Fearing hell or hoping for paradise; to such a person, God's generosity shall grant avoidance of hell or entry into paradise. The striving of the soul for God is the khidmah or muruwah of Marwah.]
