“There is no part of man that will not disintegrate, apart from a single bone at the base of the coccyx, from which he will be recreated on the Day of Resurrection.” (Using translation from Ibn Mājah 4266)
قَالَ رَسُولُ اللهِ ﷺ يَبْلَى كُلُّ شَيْءٍ مِنَ الْإِنْسَانِ إِلَّا عَجْبَ الذَّنَبِ وَفِيهِ يُرَكَّبُ الْخَلْقُ يَوْمَ الْقِيَامَةِ
