The ruling on the imam saying “Stand in straight rows” and straightening the rows

The questioner:
May Allah bless you. The brother says: If the imam says, “Stand in straight rows, may Allah have mercy on you,” or “Straighten up, may Allah keep you safe,” and he says this constantly, what is the ruling on this phrase? And what is the ruling on straightening the rows?

The Shaykh:
Yes, the imam straightens the rows by word and by action. He corrects them and encourages closing the gaps and bringing the rows and the worshippers closer together. This is part of his duty. He says, “Stand in straight rows,” “Straighten up,” “Straighten the rows,” “Do not create disorder,” “Fight against disorder among yourselves,” and “Align your shoulders.” These are phrases reported from the Messenger (peace and blessings be upon him) regarding this matter. He does not add anything from himself, may Allah have mercy on you, such as “May Allah forgive you” or the like. This is an addition that has not been reported, to my knowledge. Yes.

The questioner:
And straightening the rows. What is the ruling on straightening the rows?

The Shaykh:
It is obligatory for the imam to straighten the rows, and he does not say the opening takbir until he sees that they are straight. Yes.
