What is the ruling on the prayer of one who follows the imam in the courtyard of the mosque via the loudspeaker?

Question : This questioner is Fahd al-Harbi. He says: In one of the mosques, I found people—he says people, in the nominative or the genitive, I do not know—praying in the courtyard of the mosque, 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 they are ordered to repeat it, knowing that this may happen repeatedly?

Answer : They are not ordered to repeat it, and there is no blame on them, because the mosque is one, even if the imam and the follower do not see each other.
