Advice to the one who says that tawhid (the oneness of Allah) divides the Ummah

Question:
The questioner says: What is your advice to the one who says that tawhid (the oneness of Allah) divides the Ummah, and who says, "Let us first unite, and then we will teach the people"?

Answer:
Except for the one who acts with insight. Tawhid (the oneness of Allah) is what unites the Ummah, my brother. The Ummah has never gathered except under the banner of "La ilaha illa Allah" (There is no god but Allah). Before the coming of the Messenger and the call to "La ilaha illa Allah," they were divided, fighting and warring with one another, and . It is tawhid (the oneness of Allah) that unites the Ummah: worshipping Allah alone, with no partner for Him. Shirk (associating partners with Allah) and bid'ah (religious innovations) divide the Ummah. The false madhahib (schools of jurisprudence) and the da'wah (calling) methodologies they call by that name are what divided the Ummah. The path of the Ummah is one, and its methodology is one. What divided the Ummah was shirk (associating partners with Allah), the means of shirk, and the innovated, newly introduced methodologies. Each group makes for itself a methodology, saying, "The methodology of da'wah (calling) is the methodology of the Messenger (peace and blessings be upon him), not what you invent, nor what your leader invents, nor what your followers invent." Yes.
