Is it permissible to break the prayer to fill a gap in front of me?

Question:
He says: When we line up for prayer and the imam has said the takbir, I find a gap in front of me in the row. Do I move forward to fill it while I am praying, or do I break my prayer, move forward, and then say the takbir?

Answer:
No, do not break your prayer. It is not permissible to break the prayer. However, it is permissible for you to move forward a few steps and fill the row in front of you; there is no harm in that.
