Say to them, "Whoever is enemy to Gabriel, should understand that he has, by Allah's command, revealed to your heart the Qur'an which confirms what was revealed before it, and brings Guidance and glad tidings to the Believers. 97 Whosoever is an enemy to God and His angels and His Messengers, and Gabriel, and Michael - surely God is an enemy to the unbelievers.' 98 We have sent down clear signs to you and no one will reject them except the wicked. 99 Is it not [true] that every time they took a covenant a party of them threw it away? But, [in fact], most of them do not believe. 100 And when there came to them a messenger from Allah, confirming what was with them, a party of the people of the Book threw away the Book of Allah behind their backs, as if (it had been something) they did not know! 101 And they follow that which the satans recited in the reign of Sulaiman; and Sulaiman blasphemed not, but the satans blasphemed; teaching people magic; and they follow that also which was sent down unto the two angels in Babil, Harut and Marut. Unto none the twain taught it until they had said: we are but a temptation, so blaspheme not. But they learned from the twain that wherewith they might separate man from his wife; and they could harm none thereby save by Allah's will. And they have learnt that which harmeth them, and profiteth them not; and assuredly they know that whosoever purchaseth it, his is no portion in the Hereafter; and surely vile is the price for which they have bartered themselves, if they but knew! 102 And if they had believed, and guarded themselves from evil and kept their duty to Allah, far better would have been the reward from their Lord, if they but knew! 103
