The Statement of Allah the Most High: "And the Trumpet will be blown, and all who are in the heavens and all who are on earth will swoon away, except him whom Allah wills..." (V.39:68)
حَدَّثَنَا عُمَرُ بْنُ حَفْصٍ، حَدَّثَنَا أَبِي قَالَ، حَدَّثَنَا الأَعْمَشُ، قَالَ سَمِعْتُ أَبَا صَالِحٍ، قَالَ سَمِعْتُ أَبَا هُرَيْرَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " بَيْنَ النَّفْخَتَيْنِ أَرْبَعُونَ ". قَالُوا يَا أَبَا هُرَيْرَةَ أَرْبَعُونَ يَوْمًا قَالَ أَبَيْتُ. قَالَ أَرْبَعُونَ سَنَةً قَالَ أَبَيْتُ. قَالَ أَرْبَعُونَ شَهْرًا. قَالَ أَبَيْتُ، وَيَبْلَى كُلُّ شَىْءٍ مِنَ الإِنْسَانِ إِلاَّ عَجْبَ ذَنَبِهِ، فِيهِ يُرَكَّبُ الْخَلْقُ.
Narrated Abu Huraira: The Prophet (ﷺ) said, "Between the two blowing of the trumpet there will be forty." The people said, "O Abu Huraira! Forty days?" I refused to reply. They said, "Forty years?" I refused to reply and added: Everything of the human body will decay except the coccyx bone (of the tail) and from that bone Allah will reconstruct the whole body.
