The ruling on some of the ma'mum (congregation) assisting the imam in straightening the rows

This is a question from a listener in Riyadh: Muhammad 'Umaran al-Ghasham says: Some of the ma'mum (congregation) go to help the imam in straightening the rows for prayer, such as saying: "Move forward, so-and-so," or "Move back, so-and-so," or "Straighten the rows." What is the ruling on straightening the rows by the ma'mum (congregation)? May Allah reward you.
Answer: There is no harm in that. This is from cooperating in righteousness and piety. The Messenger of Allah (peace and blessings be upon him) commanded straightening and aligning the rows and said: If some of the ma'mum (congregation) help the imam with those around them, observing them and commanding them to align and be compact, then this is all good. This is from the category of cooperating in righteousness and piety, and we know of no harm in it.
