How to accept that Prophet Mohammad originally taught the Universal Religion as told by You?

[Swami said “In Islam also, before the arrival of the Prophet Mohammad, there were several sub-religions. The Prophet Mohammad broke all the differences in Islam and established one God called Allah. What Adi Shankara did in Hinduism, Mohammad did the same in Islam. Hinduism became one big hall and Islam became another big hall by the efforts of both these Divine personalities.”

Swami Replied: Universal means union of small things to make a big thing. Universal also means uniting the big things to make a bigger or biggest. Thus, the word universal stands for bringing out a big Islam religion by uniting the small 300 sub-religions. Removing the walls between the rooms of a house to make it one big hall is also universality. Removing the walls between such big halls to make all the big halls united into a bigger or biggest hall is also universality at higher quantitative level. Shankara did the same in Hinduism by uniting all the sub religions in Hinduism to make one big hall of Hinduism. Mohammed did the same in Islam making one big hall of Islam. Shirdi Sai Baba united these two big halls to make a bigger hall. Swami Vivekananda added all other such big halls of the world to make one biggest hall of universal religion. The logical basis in the effort of Swami Vivekananda is supplied by the present Datta Swami.
