The Prophet salla Allahu alaihi wa sallam forbade the companions from praying between the pillars.

Therefore, you should avoid that except when there is no space in the masjid as on Friday prayer.

We have a local mosque here in Kashmir in our village. We are most of the times making Safuf during Salah in between the two Pillars it goes like that as if each piller is a person. it is allowed to do so or we must make Safuf behind or in front of these pillars so as to make full Saf of people praying salah. your kind reply would be very much appreciated.
