Al-Fajr 89:23

Wajee-a yawma-ithin bijahannamayawma-ithin yatathakkaru al-insanu waannalahu aththikra

And brought [within view], that Day, is Hell - that Day, man will remember, but how [i.e., what good] to him will be the remembrance?

and Jahannam (Hell), on that day, will be brought forward, it will be the day when man will realize the truth, but from where will he take advantage of such realization?
