As to the obligatory prayer (to be said three times
a day): Each one must say his prayer alone by himself,
and this is not conditional on a private place;
that is, both at home and in the worshipping-place,
which is a gathering-place, it is allowable for one to
say his prayer; but each person must say his prayer by
himself (i.e., not in company with others who might
recite the same words and continue the same postures
together at the same time). But if they chant supplications
(communes, etc.) together (and in company),
in a good and effective voice, that is very good.
