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 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 And We have certainly revealed to you verses [which are] clear proofs, and no one would deny them except the defiantly disobedient. 99 Why, whenever they make a promise do some of them cast it aside! Most of them do not believe. 100 And when there came to them a Messenger from Allah (i.e. Muhammad Peace be upon him) confirming what was with them, a party of those who were given the Scripture threw away the Book of Allah behind their backs as if they did not know! 101 And they follow what devilish beings used to chant against the authority of Solomon, though Solomon never disbelieved and only the devils denied, who taught sorcery to men, which, they said, had been revealed to the angels of Babylon, Harut and Marut, who, however, never taught it without saying: "We have been sent to deceive you, so do not renounce (your faith)." They learnt what led to discord between husband and wife. Yet they could not harm any one or without the dispensation of God. And they learnt what harmed them and brought no gain. They knew indeed whoever bought this had no place in the world to come, and that surely they had sold themselves for something that was vile. If only they had sense! 102 And if they had believed and guarded themselves (against evil), reward from Allah would certainly have been better; had they but known (this). 103
