when the two categories are mutually contradictory?!

Yet Allah has placed distinctive markers to tell them apart, although confusion may still arise—for a person might possess a female organ as well.

The jurists are unanimously agreed that an ambiguous intersex inherits on the basis of whatever distinguishing sign is most apparent.
For example, if the individual urinates from the place where a man urinates, he receives the share of a male; if he urinates from the place where a woman urinates, he receives the share of a female. The route of urination is one of the clearest and most common indicators of sex, being observable in both the young and the old. Urination from one organ alone shows that the individual belongs to the sex associated with that organ, while the organ that is not used is treated as a superfluous appendage or a congenital defect.

If the person urinates from both organs, the organ that discharges the greater amount is deemed determinative. Should the individual at first urinate from only one organ and later from both, we rely on the organ that was used first. If the two organs release urine at the same time and in the same quantity, the matter is suspended until another sign appears at puberty; until then the case remains ambiguous, though it is hoped that clarity will come with maturity.

Among the signs that emerge at puberty are those specific to males—such as the growth of a mustache, the growth of a beard, or the emission of semen from the penis. If even one of these signs is evident, the individual is considered male. There are also signs specific to females—menstruation, pregnancy, and the development of breasts. Should any of these appear, the individual is deemed female.

If none of the male signs nor any of the female signs become evident in the person
