Indeed, there is no doubt that reviving this Sunnah requires the formation of a new congregation that leaves aside the many separate groups now dispersed among countless mosques. Yet because the sole purpose of that new congregation is to gather all of those groups into one body—just as things were in the time of the Messenger of Allah ﷺ and the Rightly Guided Caliphs—its existence is indispensable: a single united congregation will not spring into being all at once; it can only emerge through their efforts.

A well-known axiom in the principles of jurisprudence states: whatever is indispensable for performing an obligation becomes itself obligatory.

This principle confirms the need for that congregation, for it is upon the Sunnah and its goal is to realise the concept of jamaʿah in its fullest sense—unlike those other, scattered groups.

Someone may object: “Many sincere worshippers may respond once the Sunnah is made clear to them, but surely a great number will still insist on remaining divided among the mosques, in defiance of the Sunnah and of all the legal schools. In that case, the hoped-for single congregation will still not be achieved!”
