Abu Huraira reported so many ahadith from Allah's Apostle (ﷺ) and amongst these one was this that Allah's Messenger (ﷺ) said:There is a bone in the human being which the earth would never consume and it is from this that new bodies would be reconstituted (on the Day of Resurrection). They said: Allah's Messenger, which bone is that? Thereupon he said: It is the spinal bone
