Is it permissible to pray behind a pillar to complete the row, given that there is a line for straightening the rows slightly behind the pillar, and knowing that the prayer space behind the pillar is narrow and requires moving backward when prostrating?

The Prophet, peace and blessings be upon him, commanded the straightening of rows, encouraged their connection, and prohibited their disruption. Accordingly, praying between pillars is disliked except in cases of necessity, such as a cramped mosque. However, if the the mosque is spacious, the row containing the pillars should be abandoned, and only connected rows should be used.
