Shaykh, Dr. Aḥmad Bazmool, may Allah protect him, advised (1):
[Importantly], a Muslim should be diligent in praying with his Salafī brothers, those who are holding firm to the truth, even if they are few. He should be diligent about that, and he shouldn’t be deceived that some Masjids carry larger numbers and that they have the ability to do more things.
These things are not praiseworthy and desired in and of themselves. Rather, what is sought after is the truth, traversing its path, and [being with] the people upon the truth. This is what a Muslim is concerned about, and this is what our Pious Predecessors were concerned about.
