Arrangement of the Qur’an in the Mushaf
I am very interested in the Qur’an and I have several questions regarding it:1. Muhammad (SAW) received the Qur’an not in order. So, how was it arranged in such order as in our mushaf now and then? 2. How the names of the Surahs were given? 3. As far as I am concerned, during the time of Prophet Muhammad (SAW), there was no mushaf. So, how can there exist such a ruling that some people can touch the mushaf and some people cannot?Thanks in advanced.
