2:14And when they come across those who believe, they say, “We believe”; but when they are alone with their devils, they say, “We are with you; we were only ridiculing.”

2:102And they followed what the devils taught during the reign of Salomon. It was not Solomon who disbelieved, but it was the devils who disbelieved. They taught the people witchcraft and what was revealed in Babylon to the two angels Harut and Marut. They did not teach anybody until they had said, “We are a test, so do not lose faith.” But they learned from them the means to cause separation between man and his wife. But they cannot harm anyone except with God's permission. And they learned what would harm them and not benefit them. Yet they knew that whoever deals in it will have no share in the Hereafter. Miserable is what they sold their souls for, if they only knew.
