Jins (kind or genus in fiqh)

الجنس

Jins in the language means a kind of anything. Among the jurists it names a set of different sorts. The concept governs several rulings: in zakat, animals or crops of one kind are combined toward the threshold while different kinds are not; in ribawi sales, the sameness of kind decides the rule; in salam (advance sale) the kind of the item promised must be stated; and in disputes over a usurped item, the kind of the thing is one of the points on which the parties may disagree. ^{1 2 3}
