How many Times should an Imaam Recite the Tasbeeh in Ruku and Sajdah?

Q: Salaah-404: How many times should an Imaam recite the Tasbeeh in Ruku and Sajdah?

Answer: It is Mustahab for the Imaam to recite the Tasbeeh five times because reciting it only three times would not give the Muqtadis the opportunity to recite it thrice. And Allaah knows best what is most correct.
