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 indeed sent down to you clear signs; and none will disbelieve in them except the sinners. 99 Is it not (the case) that every time they make a covenant, some party among them throw it aside? Nay! the truth is most of them believe not. 100 When a Messenger of God came to them confirming the (original) revelation that they already had received, a group of those who had the Scripture with them, threw the Book of God behind their backs as if they did not know anything about it. 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 Had they come to believe instead, and taken heed for themselves, they would surely have earned from God a far better reward. If only they had sense! 103
