It is the act leading to attracting benefit or averting harm; God's act cannot be described as kasb, He being free of gaining benefit or averting harm. Kasb is also the employing of causes by choice; this is the sense of their saying: 'kasb is the servant's directing of his power'; if asked the difference between kasb and creation (khalq), we answer: the servant's directing of his power and will toward the act, and God's producing the act following that directing, is creation; the same possible object falls under both powers, but under two distinct aspects: the act is possible of God under the aspect of production, and possible of the servant under the aspect of kasb; it does not follow that two independent causes compete over the same individual effect, which is impossible.

'To earn for someone wealth or knowledge': bring it to him.

Ibn Kamal said (al-Ta'rifat, p. 193): the act leading to attracting benefit or averting harm; God's act cannot be called kasb, being exalted above gaining benefit or averting harm. Al-Raghib said (al-Mufradat, p. 430): kasb is what man selects of what carries benefit and gain; it is also used of what is thought beneficial then proves harmful; kasb covers what one acquires for oneself and for others, while iktisab is said only of what one acquires for oneself.
