They disagreed over the case of slaves on a number of issues. The first, as we have mentioned, is the obligation of his zakat on his master if he (the slave) has wealth. This is based on the point of whether he can or cannot own something. The second case is about the slave who is a disbeliever, whether he (the master) should pay zakat on his behalf. Malik, al-ShafiT, and Ahmad said that there is no obligation of zakat on the master for his disbelieving slave. The KufTs said that he is liable for zakat on his behalf. The reason for their disagreement stems from their dispute over the addition on the issue laid down in the tradition of Ibn TJmar. This relates to his words “the Muslims”, over which Nafic has been opposed, as Ibn TJmar being the narrator of the tradition also held the opinion that zakat is to be paid on behalf, of disbelieving slaves. There is another reason for the disagreement and that is whether the obligation of zakat on the master for his slave is due to the fact that the slave is a mukallaf or whether he is property. Those who maintained that it is due to his being a mukallaf stipulated that being a believer is a condition, while those who said that it is due to his being property did not stipulate it. These latter jurists said that this is indicated by the consensus of the jurists that if the slave is freed and the master has not paid zakat al-fitr on his behalf, it is not obligatory for him to pay as in the case in expiation. The third issue is about the mukdtab. Malik and Abu Thawr said that-the master is to pay zakat al-fitr on his behalf. Al-Shafi T, Abu HanTfa, and Ahmad said that c he is not obliged to pay on his behalf. The reason for the disagreement emanates from the vacillation of the case of the mukdtab between a freeman and slave. The fourth is the case of slaves acquired for trade. Malik, al-ShaficT, and Ahmad held that the master is obliged to pay zakat al-fitr on their behalf, while Abu HanTfa and others besides him said that there is no sadaqa payable for slaves owned for purposes of trade. The reason for the disagreement arises from the conflict of analogy with the general implication (in the tradition). This is so as the general implication of the word slave (used in the preceding tradition) implies the obligation of zakat for slaves owned for trade as well as others. In Abu HanTfa’s view this general implication is restricted by analogy, and that is due to the convergence of tw'o kinds of zakat in a single type of wealth. They disagreed, likewise, in the case of slaves owned by slaves and the cases under this topic are many.
