As Islam says humans should not pray to anybody other than Allah. It condemns worshipping idols. Islam says God is almighty, he has no form. My doubt is when there is no form, how can you define whether he is a male or a female? Can we refer to him as "she"?
NOTE: I have never read Quran, I just got this doubt as a flash in my mind yesterday while I was reading some book. It's just my doubt, if the answer is in the Holy-book, please refer to that, I will read and understand.
