Arabic (Original)
وَعَنْ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَنَّهُ قَالَ يَأْكُلُ التُّرَابُ كُلَّ شَيْءٍ مِنْ الْإِنْسَانِ إِلَّا عَجْبَ ذَنَبِهِ قِيلَ وَمِثْلُ مَا هُوَ يَا رَسُولَ اللَّهِ قَالَ مِثْلُ حَبَّةِ خَرْدَلٍ مِنْهُ تَنْبُتُونَ.
English Translation
And from the Messenger of God (peace and blessings be upon him), that he said: "The earth consumes everything of a human being except the tailbone." It was said: "And what is that like, O Messenger of God?" He said: "Like a mustard seed — from it you will be regrown."
