3 stages made me believe in Islam: 1-atheism

[annatar]

do you think that according to islam we must have blind faith and not to reason and use logic??

Yes..
Actually according to quran you shouldn't be here either,

And it has already come down to you in the Book that when you hear the verses of Allah [recited], they are denied [by them] and ridiculed; so do not sit with them until they enter into another conversation. Indeed, you would then be like them. Indeed Allah will gather the hypocrites and disbelievers in Hell all together -
Nisa 140.(4.140)

So muhammed iis afraid of us for we will uncover his lies..
