What is the reason for Ibn Mas'ud's (may Allah be pleased with him) disapproval of the collective dhikr circle?

The questioner : ... .

The Shaykh : No, because I have spoken about it repeatedly regarding the story of Ibn Mas'ud... in this third session... Ibn Mas'ud disapproved, as we have mentioned repeatedly, of certain things in the previous story. First, that man who took the lead and acted as a shaykh, what is his shaykhiyyah (spiritual rank) over the people of the circles? Is he teaching them fiqh? Is he teaching them the Qur'an as it was revealed? None of that at all. He is a legislator in his own right, saying to them: "Recite tasbih a hundred times." Why not fifty? Why not a hundred and ten? So this leader emerged, and those around him had to submit to him. He is a legislator . The simplest, most ignorant person, if he sits alone, can remember Allah (Mighty and Majestic) with whatever dhikr is easy for him. He is absolutely capable of doing so, unlike Hajj, for example, where a person who has never performed Hajj in his lifetime needs someone to train him, teach him, and guide him. Everyone can raise their hand and say "Subhan Allah" a hundred times, less or more, according to their time. Likewise with "Alhamdulillah." So this man took the lead over the group and assumed a shaykhly role. When Ibn Mas'ud came, he disapproved of him, asking why he was taking the lead over the group in something they do not greatly need. This is one of the images of what Ibn Mas'ud disapproved of in these people.
The second image: Where did this man get the number from? There are adhkar in the absolute Shari'ah, and they remain absolute. There are other adhkar that are restricted, and we must adhere to the number in them, neither increasing nor decreasing. This is, of course, known to you, as it came in "Sahih al-Bukhari" and others: . So this man who took the lead over the group, instead of coming to teach them the Sunnah, says to them: "It came in the hadith thus and thus." Then, when each of them finds the appropriate time or free time, or what they call "tajalli" (manifestation), meaning he turns his heart to Allah (Mighty and Majestic), he sits and remembers Allah with whatever is easy for him, whether it is a verse of the Qur'an, a surah, or a dhikr like this one that has this virtue and this specific number.
In addition to these two matters mentioned, these dhikr circles divert people from what they need more than this unlegislated gathering, which is knowledge. Therefore, you find that the people who turn to these circles, which they call dhikr or sending blessings upon the Messenger, in large numbers, most of them do not know or understand anything of Islam. They attend the circles of dhikr; the true dhikr, which involves studying the Qur'an and studying the Sunnah that explains the Qur'an, but they shun it: . The gatherings of dhikr are not only when two or three people gather and remember Allah (Mighty and Majestic) in secret and with good manners. It is not only that, but studying the Qur'an and studying the Sunnah is also among the gatherings of dhikr. And this is much more important than those gatherings. The legislated gatherings of dhikr are these, while others are not legislated. Today, the situation has reversed; people do not turn to gatherings of knowledge at all. Especially since some of those who assume shaykhly roles have told them that knowledge is a veil, and that it is better to remain ignorant than to become a scholar! So this is knowledge as a veil. Therefore, you find that most of the Sufis have no knowledge, not even this traditional knowledge...
