Is it permissible to follow a masbuq (one who joins the prayer late)?

Question:
May Allah reward you. This questioner says: Does it happen that after the congregational prayer has ended, a person comes and prays with a masbuq (one who joins the prayer late) and takes him as his imam? Is this action permissible? And what is the ruling on his prayer?

Answer:
This is not acceptable. It is not acceptable for a masbuq (one who joins the prayer late) to come, complete what he missed of the prayer, and then for someone to take him as an imam. Because the masbuq (one who joins the prayer late) is a ma'mum (one praying behind the imam), and a ma'mum (one praying behind the imam) does not become an imam unless the imam appoints him as a substitute. If the imam appoints him as a substitute, he becomes an imam. But for him to appoint someone without the imam's appointment, this is not correct. So whoever comes and has missed the prayer should wait. If someone comes who has missed the prayer like him, he prays with him. Otherwise, he prays alone. Yes.
