The Ruling on the Specific Group Dhikr of Islamic Groups

Question:
There are many Islamic groups that have specific dhikr routines, such as the Muslim Brotherhood and the Tablighi Jamaat. What is the ruling on that?

Answer:
It is prescribed for the believers to remember Allah as the Messenger (peace and blessings be upon him) did, and as his Companions did. They follow what came in the texts, and they remember Allah in the morning and evening, each one for himself. He remembers Allah to himself in the morning and evening, he glorifies Allah, he praises Him, he reads the Qur'an, he makes supplication. This is prescribed. As for making this a special system, a collective voice, in the morning or evening or at any time, or a special organization, if it was not done by the Messenger (peace and blessings be upon him), I do not know it. And you have heard in the seminar what Ibn Mas'ud did when some of the Companions came to him and said, "We saw such and such in the Dome Mosque. We saw people in circles, and one of them was saying to them, 'Say Allahu Akbar thus,' and 'Say La ilaha illa Allah thus,' and 'Glorify Allah thus,' and they were counting with pebbles." Mas'ud came to them with a changed countenance and said, "You are indeed upon a religion, O people, other than the religion of Muhammad, or you have opened a door of misguidance." They said, "O Abu 'Abd, we intended nothing but good." He said, "How many a man has been guided whom we have not guided?"
So he forbade them from this action and ordered them to proceed as the Messenger of Allah (peace and blessings be upon him) proceeded, and as his Companions proceeded. And if I were to guarantee for you, he said, "Count your sins, and I guarantee for you that none of you will be misguided, and that your halal would be something." Then I intend to denounce them in the first covenant, from the beginning, in the beginning,
