I'm curious what made you people lose faith in islam?
For me, I started losing faith ever since I was 10 years old, when I heard those stories in school I swear my eyes were rolling at how crazy they were, I used to think like "are we supposed to believe this? I could come up with a better story" lol Also I had christian best friends when I was young and I heard that only muslims are allowed in heaven and that followers of different religions will go to hell, I remember I was SO angry about this. They expected me to stop being friends with them lol. Also it's mentioned in the quran that people who convert from islam or people who lose faith should be killed immediately because they're a threat and can cause chaos. It was just clear to me early on that this a religion of hate and inequality.
Then as I got older I started to think about the stories that were told to me:
1. Prophet mohamed lived in a cave for 6 months to wonder about the beauty in this world and that there must be a creator. Why would he stay in a CAVE for 6 MONTHS to think about this? unless he really wasnt in a cave for 6 months, 6 months is plenty of time to plan out a masterpiece. He must've met with the sahaba who were probably literary geniuses and scientists and discussed his new idea. He must've thought "everybody's doing it you guys, why not us?!"
2. God the almighty releases the quran page by page, on the course of what, 20 years? Again 20 years is plenty of time to perfect the quran. Think about a group of 20 geniuses of our time group up and have a 20 years time frame to make a masterpiece, I think they would make a better book.
3. With all those stories of miracles and magic etc. you hear about why hasnt one miracle occurred in the last 500 years or more? Another proof because we only hear about them but of course we'll never witness any. I love it when people post pictures on facebook like an "allah" carved on a tree or something and people go "SUBHAN ALLAH!!" it's just so sad.
I can go on but there are too many, but those were my top reasons.
