It is narrated from Sayyiduna Abu Talhah that one day the Prophet (peace and blessings be upon him) was in an extremely pleasant mood in the morning, and signs of happiness were visible on his blessed face. The companions submitted: O Messenger of Allah! This morning your mood is very pleasant, and its signs are visible on your blessed face. The Prophet (peace and blessings be upon him) said: Yes, today a messenger from my Lord came to me and said: 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 for anyone who sends peace upon you once, I will send peace upon him ten times?
