Say (O Muhammad, to mankind): Who is an enemy to Gabriel! For he it is who hath revealed (this Scripture) to thy heart by Allah's leave, confirming that which was (revealed) before it, and a guidance and glad tidings to believers; 97 Whoever is an enemy to Allah and His angels and messengers, to Gabriel and Michael,- Lo! Allah is an enemy to those who reject Faith. 98 For, clear messages indeed have We bestowed upon thee from on high; and none denies their truth save the iniquitous. 99 Why is it that, whenever they make a covenant, some of them cast it aside? 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 Had they believed in Allah and practised piety, they would have received a far better reward from AIIah, if they had but known it. 103
