How is "Glory be to my Lord, the Most High" performed with the congregational movement?

It is prescribed for the worshiper to say "Subhana Rabbi al-A'la" (Glory be to my Lord, the Most High) when his seven limbs are settled on the ground. This glorification is obligatory once according to the Hanbalis, and recommended by the majority of scholars, with perfection being three times. As for the congregation glorifying together, it is an innovation (bid'ah), and what is prescribed is for each worshiper to glorify individually.
