What is the ruling on praying in the courtyard of the mosque, following the imam of the mosque?

Question : He says: In one of the mosques, I found people—whether they are in the raised area or the lower area, I do not know—praying in the courtyard of the mosque and following the imam who is praying inside the mosque with the other worshippers. These people follow him because they hear him through the loudspeaker. What is the ruling on this prayer? And are they ordered to repeat it? Knowing that this may happen repeatedly, no

Answer : They are not ordered to repeat it, and nothing is required of them, because the mosque is one, even if the imam and the follower do not see each other.
