Reflecting on the Transience of Life

As-salamu alaykum, I've been pondering the nature of life and how people around me, who don't share our faith, navigate its challenges. Living in a Western country, I'm surrounded by colleagues who aren't Muslims, and I often wonder how they find meaning and purpose without the guidance of Allah. Don't they ever stop to think that, without a higher power and the promise of an afterlife, their existence might seem fleeting and devoid of ultimate purpose? It's as if they're drifting towards an uncertain future, without a clear direction. I've noticed that many of them cope with this reality by staying busy and distracting themselves from the inevitable. Yet, I believe that some people's hearts can become hardened against the truth due to their choices and actions. But the people I work with don't seem to harbor extreme hostility towards the idea of a higher power; they just seem unaware of the tranquility that comes with submitting to Allah's will. What holds them back from taking that small step towards the righteous path, which could bring them so much peace and clarity? I'd love to hear your thoughts on this matter, and may Allah guide us all towards the truth. Jazakum Allahu khairan for sharing your insights.
