622. Commentary:
In these hadiths, the etiquette of following the imam for the follower (muqtadi) is explained: when the imam goes into bowing (ruku‘), then the follower should bow; similarly, when he raises his head, then the follower should raise his head; and when he has placed his forehead on the ground, then the follower should prostrate (sujud). It is obligatory for the follower to remain behind his imam.
