Arabic (Original)
حَدَّثَنَا يَحْيَى عَنِ ابْنِ عَجْلَانَ قَالَ حَدَّثَنَا أَبُو الزِّنَادِ عَنِ الْأَعْرَجِ عَنْ أَبِي هُرَيْرَةَ عَنْ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَنَّهُ قَالَ كُلُّ ابْنِ آدَمَ يَبْلَى وَيَأْكُلُهُ التُّرَابُ إِلَّا عَجْبَ الذَّنَبِ مِنْهُ خُلِقَ وَفِيهِ يُرَكَّبُ.
English Translation
Yahya narrated to us, from Ibn Ajlan, who said: Abu al-Zinad narrated to us, from al-A'raj, from Abu Hurairah, from the Prophet (peace be upon him), who said: "Every part of the son of Adam decays and the earth consumes it, except for the tailbone. From it he was created, and from it he will be reconstructed."
