question #1 Sahih Muslim 81a, Book 1, Hadith 151 : What is the significance of prostration in Islam and its impact on one’s spiritual status?

Alas, and in the narration of Abu Kuraib the words are: Woe unto me, the son of Adam was commanded to prostrate, and he prostrated and Paradise was entitled to him and I was commanded to prostrate, but I refused and am doomed to Hell.
