It is no coincidence that develop in parallel societies, which is provision in the Koran, for writing the Koran the Muslim before that he separates himself from the non-Muslims:
O ye who believe! Take not for friends unbelievers rather than believers. Do ye give Allah a manifest proof against yourselves? Surah 4.144.
O ye who believe! Take not the Jews and the Christians for friends. They are friends to each other. And whoever of you takes them to friends, truly belongs to them. Verily, Allah guides not a people unjust way. Surah 5.51.
The Koran is the revelation of Allah, and thus to be taken literally: separation of the non-Muslims wherever possible, so the formation of a parallel society is imperative for the Muslim.
