Islam in the twentieth century

The armies of the Romans and the armies of the Persians were not devoid of a belief in which they believed and would die for it, and the tribes of India or Central Asia were not ignorant of religion or neglected it in their daily living, let alone the ceremonies that accompany the religious person from his birth and do not leave him for the rest of his life.
Is it said that it was the push of the new religion that distinguished the Islamic faith over all other faiths in that conflict between countries and religions?
The push of the new religion is undoubtedly a reason that cannot be neglected in this regard, and it may come to mind to explain the strength of the call in the seventh century AD and in the twelfth century, when those carrying out the call in Central Asia were peoples of Afghans and Turks who had recently entered the religion.
But how many new faiths have done such a thing? How many times has a phenomenon like this been repeated in the histories of countries and religions?
