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 to Allah and His angels and messengers, to Gabriel and Michael,- Lo! Allah is an enemy to those who reject Faith. 98 We have sent clear signs to you, such as none can deny except those who transgress the truth. 99 Is it not [true] that every time they took a covenant a party of them threw it away? But, [in fact], most of them do not believe. 100 And when there cometh unto them a messenger from Allah, confirming that which they possess, a party of those who have received the Scripture fling the Scripture of Allah behind their backs as if they knew not, 101 and follow [instead] that which the evil ones used to practice during Solomon's reign - for it was not Solomon who denied the truth, but those evil ones denied it by teaching people sorcery; and [they follow] that which has come down through the two angels in Babylon, Hurut and Marut - although these two never taught it to anyone without first declaring, "We are but a temptation to evil: do not, then, deny [God's] truth!" And they learn from these two how to create discord between a man and his wife; but whereas they can harm none thereby save by God's leave, they acquire a knowledge that only harms themselves and does not benefit them - although they know; indeed, that he who acquires this [knowledge] shall have no share in the good of the life to come. For, vile indeed is that [art] for which they have sold their own selves - had they but known it! 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
