How do Islam believers grow in number if it is false religion while Christianity is true?

Answer 1

Both Christianity and Islam religions are true God religions. Neither Christianity nor Islam is wrong or mistaken religion since the believers of both religions believe in God oneness without a partner or associate and without companion, son, or any equivalence. It is God will and wisdom to create people different in their physical, intellectual, and religious characters; not to be enemies but to cooperate together for the benefit of our universe and benefit of mankind and to compete in doing good for themselves and their societies.

God says in Quran (meaning English translation):

{Say, "O People of the Scripture, (Christians and Jews) come to a word that is equitable between us and you - that we will not worship except Allah (God) and not associate anything with Him and not take one another as lords instead of Allah (God)....} [Quran, chapter 3, verse 64].

God says also in Quran:

{O mankind, indeed We have created you from male and female and made you peoples and tribes that you may know one another. Indeed, the most noble of you in the sight of Allah is the most righteous of you. Indeed, Allah is Knowing and Acquainted. (13)} [Quran, chapter 49, verse 13}

And God says:

{And We have revealed to you, [O Muhammad], the Book in truth, confirming that which preceded it of the Scripture and as a criterion over it. ..... Had Allah willed, He would have made you one nation [united in religion], but [He intended] to test you in what He has given you; so race to [all that is] good. To Allah is your return all together, and He will [then] inform you concerning that over which you used to differ. (48)} [Quran, chapter 5, verse 48]

and God says:

{Indeed, those who believed and those who were Jews or Christians or Sabeans [before Prophet Muhammad] - those [among them] who believed in Allah and the Last Day and did righteousness - will have their reward with their Lord, and no fear will there be concerning them, nor will they grieve. (62)}

[Quran, chapter 2, verse 62]
