Dear Brother / Sister,

1- In ruku (bowing), it is sunnah to say “Subhana Rabbiyal a’la” (Glory to my Lord, the Most High) three times and "Subhâna rabbiyal adhîm" (Glory to my Lord the Great) three times in sajdah (prostration).  These can also be said five or seven times. It is makrooh (abominable) to say them fewer than three times or not say at all. In congregational prayers, it is more appropriate for the imam to say these glorification words three times.

2- While praying, it is sunnah for the congregation (jamaah) to recite takbirs silently after the imam. Besides, when the imam says "Sami’a’llahu li-man hamidah" (God hears him who praises Him), the congregation (jamaah) silently says “Rabbana wa-laka’l-hamd” (Our Lord, and to You is all praise).
