Vocabulary of the two ḥadiths
• Surplus water (fadl al-māʾ): water that is more than a person’s own need.
• Dirāb al-jamal: with a kasra on the ḍād. It denotes the male camel’s semen discharged into the womb of the female; what is prohibited is charging a fee for it.
• ʿAsb: with a fatḥa on the ʿayn, a sukūn on the sīn, and ending with a single bāʾ. Both dirāb and ʿasb refer to the semen of the male animal discharged into the female. Some scholars define ʿasb al-faḥl as the hire taken for allowing the male to cover the female—this is the sounder view, for the act of mating itself is not forbidden.
Abu ʿUbayd said: In the ḥadith, ʿasb means hire. The soundness of his view is supported by al-Shāfiʿī’s wording: “He forbade taking payment for ʿasb al-faḥl.”
Al-Qāmūs likewise states that the object of the prohibition in the ḥadith is the fee collected for the male’s mating.
• Al-faḥl: the male of any animal—whether camel, sheep, goat, horse, or otherwise.
