The Ruling on Walking during the Prayer in Order to Close up a Gap in the Ranks
Question :
If I saw a gap in the row in front of me, is it permissible for me to move in order to close up the space if I have already made the opening Takbir?
Answer:
It is permissible to advance to the row in front of you, in order to fill a gap, because this is considered to be connecting the ranks, and whoever joined a row, Allah will establish a connection to him. This is so, even if it required one to take a step or two, because this is a small movement, which is harmless. And Allah knows best.
