Straightening the rows and the imam’s alerting the worshippers

Question:
This questioner says: If the iqamah is called and the first row is not yet complete, and the imam alerts them once, twice, and three times, but those in the second row do not respond, especially since some of them are non-Arabs, is there any blame on the imam for this?

Answer:
As long as the imam has done so, he has fulfilled what is required of him. If they are non-Arabs and do not understand the speech, then there is no blame on the imam, and there is no blame on them either, because they do not understand what is being said to them. As for the one who understands the speech and remains in the back row while there is a gap in the row in front of him, he has neglected an obligatory duty, which is filling the gaps and the spaces in the rows. Yes, and it is required of the imam that he not say the takbir until the first row is complete, just as the Prophet (peace and blessings be upon him) cared about the rows and did not say the takbir until they were perfectly straight and complete. So the imam should not hasten to say the takbir.
