ذَٰلِكَ ٱلْيَوْمُ ٱلْحَقُّ ۖ فَمَن شَآءَ ٱتَّخَذَ إِلَىٰ رَبِّهِۦ مَـَٔابًا
Zaalikal yaumul haqqu faman shaa-at ta khaaza ill-laa rabbihi ma-aaba
That is the Day of Truth. So whoever wishes to do so should take the path that leads to his Lord.
That is the day of truth. Whoever wills, let them take a way back to their Lord.
Al-ḥaqq carries the real as much as the true, so the day is being named the one item in the account that is not hypothetical. Ma'āb, the word for what a person may take toward their Lord, is a place of return, from the root for coming back, which makes the invitation a homecoming rather than a first arrival. The choice is handed over immediately after a scene in which almost no one is permitted to speak.
