Then they turned back from them, and they said: ‘Sprite-affected taught one.’
The Meccan pagans were raising the allegation that the Lord’s Book was sorcery and that it was taught to Muhammad by someone, and thus Muhammad had become a Jinn (sprite)-affected man. This was the same allegation raised by all people towards the Messengers deputed to them and the Message they were sent with, as explained in verses 15:6, 11; and 36:30.
Today, the Arabic Quran reading Fujjar all over the world, while accepting the names of Messengers and Prophets, but leading a life opposite to the Message of Adhikr, are killing the Prophets as explained in verses 3:21-22. If they are mentioned as the worst creatures among 1000 communities of the Lord’s creatures in verse 8:22, then in verse 98:6 they are mentioned as the worst creatures in the land. See explanation 38:8; and 51:52-53.
