What is the evidence that a pillar or the minbar renders the row to its left invalid in prayer? Is the ruling in this case based on independent legal reasoning?

The Shaykh : What is the evidence that a pillar or the minbar renders the row to its left invalid in prayer? And who said that the prayer is invalid in this state? This is an error. Is the ruling in this issue based on independent legal reasoning or not? And which scholars said this? And where can this research be reviewed?
It can be reviewed in the book "Ihya' 'Ulum al-Din" by al-Ghazali.
Does the prayer become invalid if the worshipper is forced to stand between the pillars—for example—during the crowding on Friday?
The prayer does not become invalid, neither in a state of crowding nor in a state without crowding. Rather, the Messenger (peace and blessings be upon him) prohibited the row between the pillars. This does not... invalidate the prayer. Rather, the prohibition is against straightening the row between the pillars, and this is when it is possible; that is, when there is space and room in the mosque. But if there is crowding, as on Friday for example, it is sufficient for you, who are eager not to disobey the command of the Messenger (peace and blessings be upon him), or eager not to commit what the Messenger (peace and blessings be upon him) prohibited, to move forward or backward. And let others who do not care at all about this disobedience, even if there is room in the mosque, form the row between the two pillars. So the matter is easy in the case of crowding.
