What is the meaning of the Hadith of the Messenger of Allah, peace and blessings be upon him: "Prayer, prayer, and what your right hands possess"?

The meaning of the Hadith is the Prophet's (peace be upon him) emphasis on preserving prayer at its appointed times and fulfilling the rights of what one possesses, whether human or animal. The Hadith has been narrated with different wordings, including "Prayer and what your right hands possess" and "Prayer, prayer, fear Allah concerning what your right hands possess."
