Arabic (Original)
وَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِنَّ فِي الْإِنْسَانِ عَظْمًا لَا تَأْكُلُهُ الْأَرْضُ أَبَدًا فِيهِ يُرَكَّبُ يَوْمَ الْقِيَامَةِ قَالُوا أَيُّ عَظْمٍ هُوَ قَالَ عَجْمُ الذَّنَبِ.
English Translation
The Messenger of Allah (peace be upon him) said: 'There is a bone in the human being that the earth will never consume. From it, he will be reconstructed on the Day of Resurrection.' They asked: 'Which bone is it?' He said: 'The tailbone (coccyx).'
