We see some people when they need to break [away from] their prayer [short] for some emergency, or to join [the congregation when] the imaam [is about to start the prayer], or if they have invalidated their prayer – they do the tasleem. So is this act [of theirs] correct, or will the intention [to terminate the prayer] suffice?
Whilst in mid-prayer, if he remembered [not having made] the intention, is it sufficient that he then makes the intention whilst he is praying?
Regarding [pronouncing] the takbeer in the masaajid, should one of the people make the takbeer and [the rest of] the people [follow by] making the takbeer after him?
I remained for forty years, and never [once] missed the initial takbeer [upon beginning the congregational prayer], except the day when my mother passed away.
