Hazrat Abu Talha narrates that the Messenger of Allah (peace be upon him) came one day while signs of happiness were visible on his face. He said: A certain angel came to me and said, "O Muhammad! Are you not pleased that for anyone from your Ummah who sends blessings upon you once, I will send mercy upon him ten times, and whoever sends peace upon you once, I will send peace upon him ten times?" The Prophet (peace be upon him) said, "Why not!"
