God Almighty said: Whoever performs the Umrah until the Hajj, then whatever sacrificial animal is feasible of sacrificial animals, there is no disagreement about its obligation, and they differed regarding the obligation. The majority of scholars are of the opinion that whatever sacrificial animal is feasible of sacrificial animals is a sheep, and Ibn Umar said that the name of sacrificial animal is not applied to camels and cows, but the meaning of the Almighty’s saying is: A cow that is smaller than a cow or a camel that is smaller than a camel is easier than the sacrifice. What I say is that if he sacrifices a chicken, that is sufficient. They agreed that this expiation is in order, so fasting does not take place until after he does not find a sacrificial animal.
