So the Commander of the Faithful عليه السلام, peace be upon him, also, when he objected, Imam عليه السلام objected to the gathering itself and did not object to the prayer itself. But when Imam Ali عليه السلام saw that the matter would be corrupted for him and that the people would be led into discord, Imam Ali عليه السلام permitted it and ordered them to pray according to their custom. So all of this is clear, praise be to Allah سبحانه وتعالى.
