He will admit to His mercy whom He wills and as for the wrongdoers -- He has prepared a painful torment.meaning, He guides whomever He wishes and He leads astray whomever He wishes.Whoever He guides, there is no one who can lead him astray; and whoever He leads astray, there is no one who can guide him.This is the end of the Tafsir of Surah Al-Dahr. And all praise and thanks are due to Allah
