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 an enemy to God and His angels and His Messengers, and Gabriel, and Michael - surely God is an enemy to the unbelievers.' 98 (Muhammad) We have given you enlightening authority. Only the wicked sinners deny it. 99 Why is it that every time they (the Jews) make a covenant, some of them abandon it. Most of them do not even believe. 100 And when there came to them a messenger from Allah, confirming what was with them, a party of the people of the Book threw away the Book of Allah behind their backs, as if (it had been something) they did not know! 101 And they followed [instead] what the devils had recited during the reign of Solomon. It was not Solomon who disbelieved, but the devils disbelieved, teaching people magic and that which was revealed to the two angels at Babylon, Harut and Marut. But the two angels do not teach anyone unless they say, "We are a trial, so do not disbelieve [by practicing magic]." And [yet] they learn from them that by which they cause separation between a man and his wife. But they do not harm anyone through it except by permission of Allah. And the people learn what harms them and does not benefit them. But the Children of Israel certainly knew that whoever purchased the magic would not have in the Hereafter any share. And wretched is that for which they sold themselves, if they only knew. 102 Had they come to believe instead, and taken heed for themselves, they would surely have earned from God a far better reward. If only they had sense! 103
