If there is no space in the mosque, does one stand to the right of the imam?

Question : Yes, if there is no space in the mosque, meaning there is only room for two rows: the first row contains the imam and the second row contains the followers. If a man enters and finds no space except to the right of the imam, we say that this is a case of dire necessity and there is no harm in it.

Answer : If we say that one should not stand to the right of the imam, what should he do? The correct view is that he prays behind the row alone, and his prayer is valid.
