question #3 Sahih al-Bukhari 812, Book 10, Hadith 207 : How does the act of prostration on seven bones reflect the physical aspects of Islamic prayer?

The Prophet (ﷺ) said, “I have been ordered to prostrate on seven bones i.e. on the forehead along with the
tip of the nose and the Prophet (ﷺ) pointed towards his nose, both hands, both knees and the toes of both
feet and not to gather the clothes or the hair.”
