Habl al-habala (the offspring of the offspring)

Habl al-habala is, in the lexicon, the young in a she-camel's womb, and in the technical sense the offspring of an offspring. ¹

Habl is the verbal noun of a female animal conceiving. ¹

The jurists agree that selling habl al-habala is forbidden and the contract void, following the hadith of Ibn Umar. ²

The jurists differ on the forbidden sense. The Hanafis, and one Shafi'i view, read it as selling what the young will bear after it is born, an unknown item that cannot be delivered. ² The Malikis and Shafi'is read it as selling a camel for a deferred price until a she-camel gives birth and the next one in her womb does too, a sale to an unknown term. ²
