We said, "We can see the look of good news on your face."He replied, "The angel came to me and said, 'Muhammad, your Lord says, Does it not please you that no one sends blessings upon you without My sending blessings upon him tenfold, and no one sends greetings of peace upon you without My sending greetings of peace upon him tenfold?'"
