World religions does evolve. Thats how they survive. If not, more and more people would question it, based on modern ideals. Religion is not something to be taken literally. It gives you moral values. And morals evolve with time. For example though I am not an expert but I think Islam doesn't object to polygamy in men. But wouldn't give the same privilege to women. Now that might be alright in 6th century but in 21st? Would you really think GOD disfavors women?
Hadiths were given out by Islamic scholars. They used their own interpretations and prophet's actions to explain Quran. Don't you think their time (8th century) had anything to do with their interpretation.Obviously Prophet was born in 6th century. He might have dressed differently if he was born today. I find it flabbergasting that Muslims doesn't ask questions. Any questioning is immediately called Blasphemy. Its just sad.
Also its unislamic for women to work along with men. Would you be willing to accept that today? Sometimes it helps to use your mind too.
First of all, I need to understand your way of thinking when you say, "world religions does evolve". What do you exactly mean by that.
If the Prophet lived today, (depends on where) he would wear different, which suits him best. I don't say every Muslim has to wear like today Arabs, that's something I would never say and nor did I. I just said, men and women have specific areas which have to be covered, and I really care less with what they cover it, it just has to be proper.
In Islam, both men and women are equal in value before the "eyes" of Allah (swt). You can't force a man to be pregnant, and you can't force a woman to work on hard physical conditions, the western community really mix things very much. Both men and women have their own strenghts and weaknesses. Ensure that you don't mix Islam with todays Muslim families, opression of women is not a part of Islam, women have their very own rights.
If you ask me, I would prefer a society where women took care of womens work. Where hospitals had both male and female doctors, where male doctors were operating with male patients and vice versa. Same with schools and what ever comes in mind. This isn't opression either, and I believe this would've been much more effective too, both economically and psycologically.
If you believe in something, you don't question it. Or you don't believe it, you doubt it.
