The Coccyx (The Tailbone)
The Coccyx is the last bone in the vertebral column. It was mentioned in many Hadiths that this bone is the origin of humans and the seed from which they will be resurrected on the Day of Judgment and that this part doesn’t decay in the earth.
The honoured Hadiths:
1. Abu Huraira reported that The Prophet (PBUH) said: “All what of son of Adam will be eaten by the earth except the coccyx from which he was created and from which he will be resurrected " Reported by Albukhari, Al Nassaii, Abu Daoud, Ibn Majah and Ahmad in his Mousnad and Malek in his Mouattaa.
2. As was reported by Abu Huraira the prophet (PBUH) said: “There is a bone in the Son Of Adam that the earth will never eat. They said what is it Oh Prophet of Allah? He said: It is the coccyx" Reported by Albukhari, Al Nassaii, Abu Daoud, Ibn Majah, Ahmad in his book “al Mousnad" and Malek in his book “Al Mouattaa".
So the previous Hadiths are clear and contain the following facts:
1. Human are created from the coccyx.
2. The coccyx does not get decayed.
3. On the Day of Judgment, the Resurrection will be from the coccyx.
The first western scientist to discover the secret of the tailbone was a German named Hans Spemann (b. 1869 d. 1941) based at the University of Freiburg im Breisgau, Germany. He called the Primitive streak and node the "primary organizer" which clearly suggests that the tailbone was the basic place of origin of the human.
After many experiments, he concluded that there was nothing that influenced the primary organizer and it could not be destroyed.
