 في ثلثة ارباعها

“The solution of this question given by the Khowarezmian is according to the school of, and one of the methods of followers. calls the sum which the donor has to pay on account of having cohabited with the slave-girl likewise a legacy; thus, according to him, the legacy is one and one-third of thing: this is another method of school. According to, the donor has nothing to pay on account of having cohabited with the slave girl: and this is again a method adopted by the school of. After this method, one-third of the donation is really paid, whilst two-thirds become extinct: and there is no return, as the heritage has remained unchanged. According to, you proceed in the same manner as after the precepts of. Thus the heirs obtain three hundred less one and one-third of thing, which is equal to two things and two-thirds: for what he (the donor) has to pay on behalf of the dowry, is likewise a legacy. Completing and reducing this, one thing is equal to seventy-five dirhems: this is one-fourth for the slave-girl; one-fourth of the donation is actually paid, and three-fourths become extinct.”
