The ruling on repeating dhikr and supplications after the prayers behind one of the worshippers or in a group

Question:
In his final question, he says: After finishing the Fajr prayer, one of the worshippers recites the tasbih and tahlil—meaning the tasbih and tahlil, and Allah knows best—loudly. He recites the first verse of Surat al-Ikhlas loudly, then completes it quietly. He does the same with the two mu'awwidhat. Is this permissible? Or does his action bother many of the worshippers and increase their dislike of him, and he does not pray in the mosque except for Fajr and Jumu'ah?

Answer:
The dhikr after the prayer, according to what came from the Prophet (peace and blessings be upon him), came as an individual act, without there being group dhikr, or one person reciting the dhikr and others repeating after him. All of this is from bid'ah (religious innovations). Rather, the prescribed dhikr after the prayers is done individually, each person doing it for himself, not connected to others. Raising the voice with dhikr by the worshippers after the taslim is from the Sunnah, but not with the intention of group supplication, or one person supplicating and the rest listening or saying "Ameen." All of this is from bid'ah. Yes.
