Say: Whoever is an enemy to Gabriel-for he brings down the (revelation) to thy heart by Allah's will, a confirmation of what went before, and guidance and glad tidings for those who believe,- 97 whoever is an enemy of God, His angels, or His messengers, or of Gabriel or Michael, will surely find that God too is the enemy of those who deny the truth." 98 (Muhammad) We have given you enlightening authority. Only the wicked sinners deny it. 99 Is it not so that every time they made a promise [unto God,] some of them cast it aside? Nay, indeed: most of them do not believe. 100 Whenever a messenger from God has come to them, fulfilling that [predictions] which they already had, some of those to whom the Book was given have cast off the Book of God behind their backs as if they had no knowledge. 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 Yet had they believed, and been godfearing, a recompense from God had been better, if they had but known. 103
