[2:102] And they followed what the Shaitans chanted of sorcery in the reign of Sulaiman, and Sulaiman was not an unbeliever, but the Shaitans disbelieved, they taught men sorcery and that was sent down to the two angels at Babel, Harut and Marut, yet these two taught no man until they had said, "Surely we are only a trial, therefore do not be a disbeliever." Even then men learned from these two, magic by which they might cause a separation between a man and his wife; and they cannot hurt with it anyone except with Allah's permission, and they learned what harmed them and did not profit them, and certainly they know that he who bought it should have no share of good in the hereafter and evil was the price for which they sold their souls, had they but known this.
[72:7] And that they thought as you think, that Allah would not raise anyone:
[72:8] And that we (Jinns) sought to reach heaven, but we found it filled with strong guards and flaming stars.
[72:9] And that we used to sit in some of the sitting-places thereof to steal a hearing, but he who would (try to) listen now would find a flame lying in wait for him (after the Prophets visit to heavens)
