I was reading about something in genetics and it shook my iman. I am not sure why because genetics could really strengthen Iman in Allah SWT. But I now understand that I need to strengthen my iman but in a different way where my iman will never Be shaken and it’ll be like a mountain. I hope I get to that spiritual stage. What is your advice?

I recommend seeing the following:
