Yosef Karo

“ After the circumcision, we say Ashrei (the custom is to circumsize after Ashrei (Minhagim) ) . If [the baby] is in a place that they will need to leave the synagogue, the circumcision is not done until the Torah is returned. ”

“ The practice is to fall on our faces when we say "and the priests and nation" and also in "aleinu l'shabeach." The hazzan is forbidden to move from his spot during prayer to fall on his face. We should stop those who do this. ”
