Pointless to Warn
When hardship touches a person, they call upon Us, lying down, sitting, or standing. But when We remove their hardship, they continue as if they had never called upon Us for relief. This is how the deeds of the transgressors seem fair to them.
10:12And if misfortune touch a man he crieth unto Us, (while reclining) on his side, or sitting or standing, but when We have relieved him of the misfortune he goeth his way as though he had not cried unto Us because of a misfortune that afflicted him. Thus is what they do made (seeming) fair unto the prodigal.
