And when the punishment was established and its day was made clear, He made clear its people by His saying, causing it to be understood: "So woe" is a word they say to one who has fallen into destruction. Its meaning is the arrival of a disgraceful evil in which there is lamentation and grief. "On that Day" means the day when what has been previously mentioned will occur. "For the deniers" refers to those who are deeply entrenched in denial, and they are those who died while attributing the truthful ones to falsehood.
