The ruling on placing one's foot against another's foot in the prayer row

Question:
The questioner asks: What is the ruling on placing one’s foot against another’s foot in the row, especially since it sometimes distracts from khushu' (humility) in the prayer?

Answer:
If it harms the people praying by crowding them with his foot against their feet, it is not permissible. However, they should not leave gaps; they should align their shoulders and ankles, and they should not leave spaces for Shaytan, as the Prophet (peace and blessings be upon him) said: It is not to be spread out. He does not spread out; he keeps his legs close together. No, they should be close to one another, so that there is no space between them. Yes.
