"This, because ye used to take the Signs of Allah in jest, and the life of the world deceived you:" (From) that Day, therefore, they shall not be taken out thence, nor shall they be received into Grace. Al-Jathiyah 45:35 ⧉
Tafsir:
In the present world when a man commits evil, its bad results do not at once appear before him. This serves to embolden him. When he is warned about his bad deeds, he is not prepared to give any serious attention to this. But, in the Hereafter, the consequences of his misdeeds will appear before his eyes and he will be completely engulfed in them. At that time he will accept the Truth, which he had formerly ridiculed as being worthless. In the Hereafter, man will accept the Truth which he denied in this world. But this will carry no weight there, as it is only acceptance of Truth at the ‘unseen’ level which is of value, not acceptance after the revelation of Reality.
