Why two sacrifices for the poor 2786538134

According to the Shari'ah, it is obligatory to sacrifice any one animal in the custody of the person who owns the nesab of sacrifice. It is not necessary to sacrifice any particular cow or goat. So if the sacrificial animal of a rich person is lost or stolen, another purchase will be made from his custody. After getting the lost animal, it does not have to be sacrificed. On the other hand, sacrificing in the custody of the poor is not obligatory according to the Shari'ah. However, if he buys an animal for the purpose of sacrifice, then it becomes obligatory on him to sacrifice that particular animal. Because, for the poor, buying animals for sacrifice is a kind of vow that must be fulfilled. And since it was already obligatory on him to sacrifice the lost animal, he must also sacrifice it after receiving it. That is, both have to be sacrificed. 3212952694
