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 the enemy of God and His angels and apostles, and of Gabriel and Michael, then God is the enemy of such 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 And whenever there came unto them an apostle from Allah confessing to that which was with them, a party among those who were vouchsafed the Book cast Allah's Book behind their backs as though they knew not. 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
