Question:
After the end of the prayer, we perform a collective supplication. Is what we do permissible?

Answer:
After the iqamah of the prayer, or after the prayer. After the end of the prayer. After the end of the prayer, collective supplication is not permissible in any circumstance. Collective supplication, where a group recites with one voice, or one person supplicates and then they follow him, he teaches them and then they follow him, this is a bid'ah (religious innovation), whether after the prayer or in a state other than that, whether after the prayer or during tawaf (circumambulation of the Ka'bah), or otherwise.
Collective supplication is a bid'ah (religious innovation). What is prescribed (mashru') is for each Muslim to supplicate for himself alone, for each Muslim to supplicate for himself, his brothers, his parents, his brothers, and the Muslims, for himself alone, without being tied to collective voices and intonations until it becomes as if it were songs. This, in addition to being a bid'ah, is also something that resembles songs and resembles the innovated Sufi chanting.
Therefore, it is obligatory to abandon this custom and stay away from it, whether after the prayer or in a state other than that. All collective supplication is a bid'ah in any state it may be. Yes. May Allah reward you with good, and may He do you good.
