To warn those who are alive, and so that the retribution will be deserved by the ingrates.
Translation endnotes
[36:70] It is an implicit and ironic prophecy of the Quran that the chapter containing the only verse stating that the Quran was revealed to remind the living people, has been dedicated to dead people. Those who follow hadith and sectarian teachings recite this chapter in funerals. In opposition to the Quran, "living" people recite these verses for the dead, who do not hear. According to the Quran, those people are no different than the dead people. A class of people getting paid for reciting a book that they do not appreciate nor understand over the dead people who also do neither, is one of the strangest affairs.
