Is it true that sending messages saying: “Send salutations upon the Prophet ten times, then send it to others” is a religious innovation (bid'ah)?

Question:
He says: Honorable Shaykh, may Allah grant you success. I sent a message stating that I asked whoever received it to send it to ten people, and the message was: “Send salutations upon the Prophet Muhammad (peace and blessings be upon him) to others so that you may receive reward.” One of the people I sent it to objected to me and said that there is no evidence for this action and that it is a bid'ah (religious innovation). Is his statement correct?

Answer:
Yes, he has some validity in this, because saying “distribute it to ten, to a hundred, or to five”—first, sending it via mobile phone has no necessity; why go to that trouble? If you see someone, tell him: “My brother, sending salutations upon the Prophet (peace and blessings be upon him) is prescribed (mashru') and has merit. There is no need for you to send it, neither by mobile phone nor by a letter you send.” And saying “to ten, to five, to fifteen”—this has no basis. Yes. And I do not want this door to be opened, because the superstitious will enter and spread their evil through mobile phones. Yes.
