Man Was Created From Coccyx (Tailbone)
قال رسول الله صلى الله عليه وسلم قال : كل ابن آدم تأكل الأرض إلا عجب الذنب ، منه خلق وفيه يركب.
The Messenger of Allāh ﷺ said: “All of the son of Ādam is eaten by earth (after death) except for the tail-bone, from it he was created and on it (he) will be reconstructed (on the Day of Judgement).”
