ANSWER:
This is all baseless!
The concept of trinity is found in Christianity and it was taken from the pagans after distorting and altering the Bible. This concept doesn’t exist in any of the previous religions prior to Christianity. Not only that, it goes totally against the fundamentals of monotheism that all religions came up with which clearly indicates that it is fabricated and man-made. It is not even logical nor acceptable to normal human beings and this is why hundreds of thousands are abandoning it and accepting Islam.
Number three exists like all other numbers around us. Therefore, you can find examples for number one in the number of prophets sent to the Muslims; Prophet mohammed. You can find number two in his best companions; Abu Bakr and Omer.
We can go on and on but all these numbers have no significance at all!
There is only One Creator who is alone worthy of being worshiped. He has no associates and needs no one while everything in this universe needs Him and is dependent on Him.
