Why Islam is Propagating so Fast?
Although it’s a good news, but I think you are exaggerating a little bit, 2050 is still far means after 40 years, I think Islam will conquer even much earlier, we already 25% of all world population, it’s enough to have 30% as muslims, this means every house there will be one muslim at least, whether the father, mother, son, or a daughter is a muslim, and this member will do the rest of the work.
Islam is always promoting even in worst times, for many reasons:
Women and youth are the most people who accept Islam, because of its simplicity, answers, and details that satisfy any one.
Islam beliefs don’t include any mysteries or probabilities or secrets that nobody knows their answers, it is straight forward and clear like a Sun shining…
Islam has no contradictions; its concepts can be explained to a Bedouin in a desert or a framer on top of Himalayas or Technology professor in MIT or Harvard universities, all in the same way:
There is only one God who created all universe and we have to worship him, but how?
God showed us the way by his prophets, and the last one is Muhammad (PBUH), who came after Jesus.
Every prophet may have a book and rules that fit his generation and his time, till the last sent prophet.
How can you know that prophet is real one?
They all assemble a single chain: each prophet of them had talked about the one before him and prophesized about the next one coming after him.
How do you know the Muhammad is the successive of Jesus?
