The first (highest ranking) receives one-fourth. The second receives one-sixth, as she would have received one-third if she were fully free. The third receives half of the one-sixth share, according to the Basran school of thought. This is because when calculating for the lowest daughter, if both upper daughters were slaves, she would get half; if one were free, she would get one-sixth, totaling one-third. The higher ranking daughter blocks a quarter, and the middle daughter blocks half a sixth, leaving the lowest daughter with one-sixth if she were free, thus, if half her status is free, she receives half of that one-sixth.

According to another calculation ('al-Tanzīl), the third daughter receives one-half of one-eighth plus one-third of it. Some scholars aggregate the freedom statuses, resulting in one and a half portions of freedom among them, granting the first a third and a quarter, the second two quarters, and the third half a sixth. A fourth daughter would receive another half-sixth.
