What is the legal status of the offspring born to an animal designated for sacrifice?

Primary text

The offspring of an animal designated for sacrifice follows the ruling of the mother, whether the pregnancy existed at the time of designation or occurred afterward. This is established because the entitlement to the offspring arises through its dependence (*sirayah*) on the mother, so what applies to the mother applies to the offspring, similar to the offspring of a concubine (*umm walad*) or a manumitted slave by future decree (*mudabbara*). Therefore, the offspring must be sacrificed like the mother, adhering to the prescribed time frame of the days of Eid al-Adha. Evidence for this is found in the report from Ali, peace be upon him, who instructed a man who bought a cow for sacrifice that became pregnant to sacrifice both the cow and its calf on the Day of Sacrifice, as the calf fulfills the requirement for seven shares.
