tanslation of the meaning of the qur`an
(( 23:90. Nay, but We have brought them the truth (Islâmic Monotheism), and verily, they (disbelievers) are liars.
- No son (or offspring) did Allâh beget, nor is there any ilâh (god) along with Him. (If there had been many gods), then each god would have taken away what he had created, and some would have tried to overcome others! Glorified be Allâh above all that they attribute to Him!))
so now let us see
what if there is many gods >>>>
1- either each one will do what he want ,if so then each god would have taken away what he had created, and some would have tried to overcome others! (if that happen that every god will take his creation and he will be their one god) or the cosmos will be destroyed (and that dont happen)
2-or one of them will give up of some of his creation to the other ,if so then he isnt God bec a part of his creation is out of his reach ,there is also another thing the cosmos is dependant on each other so that part that he had given up will affect the part that is under his control and the reverse will occur so that mean he didnt give up of some of his creation to the other so called deity
now we believe that there is one god
let us see how many persons is God
1- we said he is many persons ,then i ask is any of them God ,if you said yes they i will say that you are polytheist (we proved that there is one god see above) if you say they dont have conflicts then i say they must be same and equal or not ? if you said they are different >>>conflicts ,if they are same then i ask you they must be repeat of each other ? if you say they are not >>>>they are different (polytheism) ,if they are same then i tell you that one is enough ,if you said no then i tell you that if that one need another one then he isnt God bec God is enough and he dont need a help ,if you said that he is enough then i tell you that the other persons are not needed (and God is needed not reverse )and so they are not God
so we see that there is one god ,and God is one person
