The Disbelievers thought that the Day of Resurrection would never come to pass

Allah tells us how the disbelievers thought that the Day of Resurrection would never come to pass, as they said:

مَتَى هَـذَا الْوَعْدُ

In verse 50, it was said فَلَا يَسْتَطِيعُونَ تَوْصِيَةً وَلَا إِلَىٰ أَهْلِهِمْ يَرْ‌جِعُونَ (So they will not be able to make a bequest, nor will they return to their household.), that is, people who are gathered there will not have the respite to make a will among themselves to do something on their behalf, and those who are still outside their houses will not find the respite even to go into their houses. They will lie dead in the very state in which they would be at that time. This is a description of the first blowing of the Horn of the day of Qiyamah as a result of which the entire gamut of the earth and heavens will be destroyed.
