And (He created) the pair of camels and the pair of cows. Say, `Is it the two males that He has made unlawful or the two females or is it that which the wombs of the two females contain (which He has forbidden)? Or were you present when Allâh enjoined this (unlawfulness and lawfulness) on you?' Who is more unjust than he who forges a lie against Allâh deliberately that he may lead the people astray without having any knowledge. Verily, Allâh does not guide the unjust people.
