Will Islam one day end and be replaced by a new religion?

No. That everything in the world has a fixed term is a general truth and proves nothing about Islam. Nowhere does the Holy Qur’an say that it will one day lose its validity. On the contrary, it says that God guards it.

Some people argue from the Holy Qur’an itself that Islam will one day be replaced. They say it teaches that everything has a fixed term. So Islam too must come to an end at some point, and a new religion will follow.

It is true that the Holy Qur’an speaks of a fixed term for everything. But it says the same about the sun, the moon and the whole universe. That everything comes to an end is something no sensible person denies. Precisely because the statement applies to everything, it proves nothing in particular. No one would conclude from it that the universe is ending right now so that some new teaching can begin.

Anyone who claims that Islam will be replaced would have to show something else. They would have to find a passage in which the Holy Qur’an says about itself that it will one day lose its validity and a new book will take its place. There is no such passage.

The Holy Qur’an says the opposite. God Himself sent it down and will guard it. No human being and no evil influence is allowed to change it. To this day its text has been preserved unchanged. As long as that remains so, its validity remains as well.

The verses above fit this. God says that He has perfected the religion and that He will make it prevail over all others. A perfected teaching whose very wording God Himself protects needs no successor.
