not working for the Hereafter

وَجِا۟ىٓءَ يَوْمَئِذٍۭ بِجَهَنَّمَ ۚ يَوْمَئِذٍ يَتَذَكَّرُ ٱلْإِنسَـٰنُ وَأَنَّىٰ لَهُ ٱلذِّكْرَىٰ

when Hell is that Day brought near- on that Day man will take heed, but what good will that be to him then?

يَقُولُ يَـٰلَيْتَنِى قَدَّمْتُ لِحَيَاتِى

He will say, ‘Would that I had provided for this life to come!’
