Not Forbidden
They say, “What is in the wombs of these animals is reserved for our men, but forbidden to our women.” But if it is stillborn, they all share in it. He will repay them for their claims.
6:139And they say: That which is in the bellies of such cattle is reserved for our males and is forbidden to our wives; but if it be born dead, then they (all) may be partakers thereof. He will reward them for their attribution (of such ordinances unto Him). Lo, He is Wise, Aware.
