(Have not those who disbelieve) in Muhammad (pbuh) and the Qur'an (known that the heavens and the earth were of one piece) We did not send down to it a drop of rain or grow vegetation on the earth which were aligned with each other (then We parted them) and then separated them and singled them out from each other through rain and plants, (and We made every living thing of water) We made of water from the male and female everything that requires water? (Will they) i.e. the people of Mecca (not then believe) in Muhammad (pbuh) and in the Qur'an?
