The Spin

Narrative A

Islam’s unmatched clarity in monotheism, its unaltered revelation, the prophetic character of its founder Muhammad, and its harmony of faith with reason all point to one truth: it is divine. In a world riddled with spiritual confusion, Islam offers certainty, rooted not in emotion but in timeless, rational, and god-ordained guidance.

Narrative B

Islam’s staggering growth isn’t driven by mass conversions or theological superiority — it’s just demographic mathematics. Muslim families have more children, their populations are significantly younger, and they retain religious identity more so than others. Migration into the West also swells numbers. In essence, Islam is growing due to population momentum, fertility, and cultural cohesion.
