The ruling on collective supplication after prayer

Question:
May Allah reward you. Also, from his questions, he says: Honorable Shaykh, I ask about the ruling on supplication after the prayer, knowing that the imam makes supplication and those behind him say “Ameen” to his supplication.

Answer:
As for them making a collective supplication, because the imam makes supplication and then they follow him and say what he says, or he makes supplication and then they say “Ameen” to his supplication, this is a bid'ah (religious innovation), and this is not permissible. As for each person making supplication for himself individually, this is prescribed and recommended that he makes supplication after the obligatory prayer, but it should not be a collective supplication. Yes.
