And he hadn’t any authority upon them except to know Us who believe in the Hereafter and those who are in doubt about It, and your Lord is the custodian upon everything.
It is warned in verse 14: 22 that Satan himself will say on the Day of Judgement that he had no authority upon mankind except to call them.
‘Except to know Us who believe in the Hereafter from the those who are in doubt about It’ doesn’t mean to know to the Three Time Knower Lord who knows the treachery of eyes and the state of hearts, but it is to know to the believer who testifies Adhikr-the Best Interpretation of Lord’s Book. Upon the believer who utilizes Adhikr as a Shield and Safeguard, Satan has no authority. It is told in verse 7: 37 that without witnessing against his soul that indeed I was a disbeliever, the Impartial Lord won’t send anyone to Hell. See explanation 6: 130, 165; 16: 99-100; 17: 45-46; 29: 1-3.
