Does advancing a few steps during the prayer harm it?

Question:
In his second question, he says: I see that some of the young men, when the imam finishes the prayer and the young man still has some units of prayer remaining, he advances a few steps forward to prevent people passing by from disturbing the other worshippers. Is his action correct?

Answer:
It does not harm him, if Allah wills... advancing a few steps so that people can pass behind him does not harm him, if Allah wills, if he has remaining prayer to make up. However, staying in his place and praying in his place is, praise be to Allah, more preferable than advancing. Yes.

The presenter: May Allah reward you with good.
