What happened to all these different cultures that did not accept Islam, Islamic sharia, and Islamic dominance? They were killed, ran off, or remained marginalized to this day.
Every Country in the MENA with the exception of Israel, are signatories to the Cairo Declaration of Human Rights:
Article 19: “There shall be NO crime or punishment EXCEPT as provided for in the Sharia.”
Article 24: “ALL the rights and freedoms stipulated in this Declaration are subject to the Islamic Sharia.”
Article 25: “The Islamic Sharia is the ONLY source of reference for the explanation or clarification of ANY of the articles of this Declaration.”
