Freedom of conscience is laid down by the Qur’ān itself: “There shall be no compulsion in [ac-ceptance of] the religion..” (2:256) The life, honour and property of all citizens in an Islāmic state are considered sacred whether the person is Muslim or not.
“O mankind, indeed We have created you from male and female and made you peoples and tribes that you may know one another. Indeed, the most noble of you in the sight of God is the most righteous of you. Indeed, God is Knowing and Ac-quainted.”
Qur’an 49:13
