[They are] eight mates - of the sheep, two and of the goats, two. Say, "Is it the two males He has forbidden or the two females or that which the wombs of the two females contain? Inform me with knowledge, if you should be truthful."
He created for you eight types: two types of sheep, male and female, and two types of goats. Say, O Messenger, to the idolaters: Did Allah make the two males unlawful because of their being male? If they say, ‘Yes,’ then ask them: Why do you regard the females as unlawful? Or did He make the two females unlawful because of their being female? If they say, ‘Yes,’ then ask them: Why do you regard the males as unlawful? Or did He make what the wombs of the two females contain unlawful because of being contained in the womb? If they say, ‘Yes,’ then ask them: Why do you differentiate between what the wombs contain by making the male unlawful sometimes and making the female unlawful at other times? Tell me, O idolaters, what proper knowledge do you base this on, if you are truthful in your claim that the prohibition for this is from Allah?
