Allama Shami (RA), quoting from the author of 'Hilyah', narrates that Hazrat Abdullah ibn Mubarak, Ishaq, Ibrahim, and Thauri (May Allah have mercy on them) state: It is Mustahab (recommended) that the Imam should recite the Tasbeehat in Ruku and Sajdah five times each, so that the Muqtadis (followers in congregation) can recite them three times each. Therefore, if the Imam does not take this into consideration, this act of his will be Makrooh (disliked). (Aham Masail / Vol: 5 / Page: 88)
