Respect your leaders appointed by God; Be humble; Remember your place in society; Serve God regardless of position or identity.

This hadith is about Abu Bakr writing a letter to someone and stamping it with the Prophet's ring. The engraving on the ring was in three lines - Muhammad, Apostle, and Allah. This shows that even though Muhammad was an apostle of Allah, he was still respected as an individual. It also shows that Muslims should respect their leaders as they are appointed by God. Furthermore, this hadith teaches us to be humble and remember our place in society - we are all servants of God no matter what our position is or who we are.
