They followed the scripture that.

They followed the scripture that Satan used to recite during Solomon's reign. Solomon did not disbelieve; It was the devils who disbelieved. They taught people sorcery and what was revealed to the two angels, Harut and Marut, in the city of Babylon. Neither of them taught anyone that we were for testing; So do not disbelieve. Then they would learn from them magic that would cause separation between husband and wife. They could not harm anyone except by God's leave. What hurts them and does them no good, they learn. They know very well that whoever practices magic has no share in the Hereafter. Evil is that for which they have sold themselves.

(Surat al-Baqarah: 102)
