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 Whoever is an enemy of Allah, His Angels, His Messengers, Gabriel, and Michael indeed Allah is the enemy of the unbelievers' 98 And certainly We have revealed to you clear communications and none disbelieve in them except the transgressors. 99 Has it not always been so that every time they made a covenant, some of them set it aside? Nay, most of them never believe in it sincerely. 100 When a messenger was sent to them by God affirming the Books they had already received, some of them put (His message) behind their backs as if they had no knowledge of 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 And if they had believed and kept from evil, a recompense from Allah would be better, if they only knew. 103
