People labour under ignorance about the beginnings of Islam and think that it came about at the same time as Christianity. Perhaps you could talk about the beginnings of Islam and when?
Islam is a very true religion in which people are ONLY said to believe ask and be scared of Allah! It is a religion which tell women to keep a distance from unknown men and coming or going outside not without a chador covering their whole body except half of the face till the nose just showing the eyes! These things are only for women safety !the holy book of Islam is Quran and what all written in it is about Allah his prophets and the things or rules that should be followed by Muslims and what all will happen to people after death and a lot of things ! And all the things written in Quran are a 100% true………
Islam almost certainly evolved from early moon worship in the same way that the earlier Abrahamic religions almost certainly evolved from sun worship. We cannot know either for certain.
