تسبّب

[as quasi-pass. of 2, (assumed tropical:) It was, or became, made, or appointed, or prepared, as a means, or cause, of attaining, or accomplishing a thing, or an affair; followed by لِأَمْرٍ. And It was, or became, caused, or occasioned]. You say, تسبّب مَالُ الفَىْءِ (assumed tropical:) [The property of the spoil, or acquisition, or tribute, termed فَىْء was caused, or occasioned, to accrue]: for that whereby the property is caused, or occasioned, [to be obtained, as the abandonment of their abodes by unbelievers, or their making peace with Muslim invaders on the condition of paying a poll-tax or the like,] is made a means, or cause, of the accruing of the property to those to whom it is due of the recipients of the فَىْء (Az, TA.) [See also 10.]

تسبّب بِهِ إِلَى شَىْءٍ (assumed tropical:) He made use of it as a means, or cause, of attaining, or accomplishing, a thing. (M.) And أَتَسَبَّبُ بِفُلَانٍ إِلَيْكَ (assumed tropical:) [I make use of such a one as a means of access to thee]. (TA in article ذرع.)

[Hence, in the present day, تسبّب is used as meaning (assumed tropical:) He trafficked; because trafficking is a using means to procure subsistence.]
