The ruling on walking during prayer to close a gap or for a need

Question:
I found that the Shaykh said that the Prophet (peace and blessings be upon him) would move during prayer when he moved or when the Qur'an was recited during the time of prayer.

Answer:
There is no leeway in that; if he finds a gap in the row in front of him, he walks to it and closes it. Walking a few steps during prayer for a need is permissible. Abu Bakrah (may Allah be pleased with him), when he entered while the Prophet (peace and blessings be upon him) was bowing, bowed behind the row, then walked and entered the row. The Messenger (peace and blessings be upon him) did not tell him to repeat his prayer or disapprove of that; rather, he said to him, "May Allah increase you in zeal, and do not do it again," meaning do not do the like of bowing behind the row. The Prophet (peace and blessings be upon him) used to open the door for Aishah while he was praying, and he would go up and down the pulpit to teach the Companions the prayer so that they could see him (peace and blessings be upon him) and follow him. Going up and down the pulpit during prayer for the sake of teaching—I bring this as evidence—indicates that slight walking for a need, such as the need for teaching, the need to open the door if it is in front of him, the need to close a gap, or to kill something that harms him, such as a snake or a scorpion, all of this is permissible in prayer.
