You say: on the day of victory the acceptance of the belief of those who disbelieved will not be benefited for them, and for them will not be granted respite.
It is stated in verse 6: 158: “What are they waiting for except that the Angels come to them, or your Lord comes, or some of your Lord’s signs come? On the Day when some of your Lord’s signs come, belief in them will not benefit any soul who has not believed in them before, or whose belief did not earn any good; you say: You wait, indeed we are also waiting.” For the individual, “the Day Allah comes” means their death, while for all mankind, it is the Doomsday. “The coming of the Angels” happens at death for the individual, whereas it is the sending down of punishment for the concerned people, and the Doomsday for all mankind. Read together verses 23: 99-100; 25: 21-30, and 39: 55-59. As for the people, “some signs from your Lord” means punishments such as drought, epidemics, earthquakes, scarcity, disturbances with locusts and lice, war, floods, cyclones, tsunamis, etc., whereas, for all mankind, it is the ten important Crucial Signs of Doomsday. The Lord of the Universe taught through Messenger Muhammad that the Last Hour would not happen until those ten signs appeared. They are the rising of the sun from the west, as explained in verse 2: 258; smoke that will spread throughout the Earth, as explained in verse 44: 10; the coming of a monster saying that indeed mankind does not have confirmed belief in the Lord’s verses, as explained in verse 27: 82; the spreading of Gog and Magog, as explained in verse 21: 96; the emergence of Satan Antichrist and the second coming of Jesus, as explained in verse 4: 159; the sinking of the earth in three places (one in the east, another in the west, and a third in the Arabian Peninsula), as warned in verses 16: 45, 28: 81, and 67: 16; and a fire from Yemen leading people to “Mahshara” (the Summoning place for the Day of Judgment), as explained in verses 21: 97 and 23: 101. With the appearance of any of these ten Crucial Signs, no soul will be benefited from its belief since the doors of repentance will be closed forever. “Any soul who has not believed in them before, or whose belief has not earned any good,” mentioned in the verse, refers to the Arabic Qur’an reading Fujjar, including hypocrites and their blind followers. Since they are reading these verses without testifying to any of them, they cannot form true belief. These people, by forgetting Adhikr—the Three-Time Knowledge—have become worthless, as explained in verses 3: 196-197. They will accept Antichrist Kafir Satan as the prophet at first to get water and food, and later even as their lord. They will enjoy his Paradise for ‘one and a quarter year,’ as explained in verse 4: 159. With the second coming of Jesus and the killing of Antichrist, all other people will accept Islam. Then the hypocrites, 70,000 soldiers of Antichrist, and those who have diseases in their hearts—having doubts—will be killed, as explained in verses 4: 91 and 33: 60-61.
The Angels will softly take back the Spirit (life + soul) of believers who fulfill the aim of life, and they will die seeing the Lord brightly and pleasantly with their souls. However, for all other people of Messenger Muhammad, the Angels will take back their Spirit roughly and rudely, as explained in verses 6: 93-94, and they will see the Kafir Satan sadly and grievously, as explained in verses 4: 32 and 6: 62. See explanation 3: 96-97.
