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 For, clear messages indeed have We bestowed upon thee from on high; and none denies their truth save the iniquitous. 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 And when a messenger from Allah came to them confirming that which was with them, a party of those who had been given the Scripture threw the Scripture of Allah behind their backs as if they did not know [what it contained]. 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 And had they but believed and been mindful of God, His reward would have been far better for them, if they had but known it. 103
