5:101 Believers, do not ask about things that if they appeared to you, would only upset you; but if you ask about them when the Koran is being sent down, they shall be made plain to you. Allah will pardon it; Allah is Forgiving, Clement.
5:103 Allah has not (ordained man) made (circumstances) cattle, a slit eared she-camel, nor a freely grazing she-camel, nor a she-camel that bore twins, nor an uncastrated camel (dedicated to idols), but those who disbelieve invent lies against Allah. Most of them do not understand.
