Those who believe, then reject Faith, then believe (again) and (again)
reject Faith, and go on increasing in Unbelief – Allah will not forgive
them nor guide them on the way.[lxxvii]
This is a striking pronouncement and almost conclusive against the thesis that an apostate must lose his head immediately after his defection from the faith. The verse visualises repeated apostasies and reversions to the faith, without mention of any punishment for any of these defections on this earth. The act of apostasy must, therefore, be a sin and not a crime. If he had to be killed of his very first defection, he could not possibly have a history of conversions.[lxxviii]
