it may sound stupid to you but I believe in islam based on faith on proofs. I have studied islam and found proofs of it, they appear to be proofs from my pov. I'm a very sceptical person and I tend to overthink matters, their was a time when I thinked religion was a lie and that people who believed in it were stupid (I'm born and raised in an islamic country). but after a major event in my life, I began to think more seriously about it then I decided that I need to have a serious answer once and for all. I remember that I thinked :
"if their is no god and if death is becoming nothing then life doesn't matter, better end it now, or do whatever the **** I want to do, everything. but if their is god and I die then I go to hell. this is a risk I'm not willing to take, I need a serious answer"
also I used to think that god is a dictator that burns everyone who disagrees with him for eternity, but then I said, if I'm wrong then I ****ed up and missed my chance to know this awesome being, and if I'm right then I'd rather be in the right side of the equation, even if he's a dictator, gotta be in the government.
its all about the risks of the positions. an atheist takes far more risks than a religious person. if the atheist is right then the religious guy doesn't loose anything, but if the religious is right the atheist looses eternity. personnaly I can't take that risk.
these were the thoughts that led me to study more about religion, I first read the taoism, having already an islamic background, I found tao REALLY similar to ALLAH. I also read extensively the quran and the life of the prophet mohammad, looking for countradictions, couldn't find any, from my pov, I also found proof in the way mohammad lived, and many scientific proofs in the quran (my pov, don't laugh at me please).
why did I choose islam over other religions ? because it is litterally the word of god through the quran (my pov), this word is recent (only 1400 years) compared to other major religions, I have proof it didn't change over time. for exemple, the whole christianism is the equivalent of the sunna in islam as it is only the transcription of the life of a prophet written by normal humans. I choose it because I couldn't find countradictions in it, not for lack of trying, that's not the case for other religions.
their is a theory by mostapha mahmoud that says that all massive religions were by the only god, as their are huge similarities between them, and because god in islam says that he will send prophets to every people/nation/culture that show them islam (litterally surrendering to god, worshiping him, living in peace) but that they end changing it to something else : for example worshiping angels as other gods. for example the vikings have odin, the father, the supreme god but they have other gods of lighning, water, death...
I have faith that the proofs that I've encountered in islam are really proofs and that I'm not mistaken, in other words, I believe that I'm right about it. but hey, what do I have to loose ? a few years living a peacefull life ? sounds like a good deal.
if their is no god then it doesn't matter what I do here. and it is very depressing.
sorry for the spelling mistakes.
