I have a question I have been involved in some discussions with some brothers regarding holding gatherings of Dhikr in Unison, they quote this Hadith as evidence to prove that it is permissible to hold Dhikr gatherings
in Unison,
It was narrated that Abu Saeed Al-Khudri said: Muawiyah, said: The Messenger of Allah [Sallallahu alayhi wasallam) went out to a circle – meaning, of his Companions – and said: What are you doing? They said: We have come together to pray to Allah and praise Him for guiding us to His religion, and blessing us with you. He said: I ask you, by Allah, is that the only reason? They said: By Allah, we have not come together for any other reason. He said: I am not asking you to swear to an oath because of any suspicion; rather Jibril came to me and told me that Allah, the Mighty and Sublime, is boasting of you to the angels.

I have read the question number 154213:
