Freedom of conscience is laid down by the Qur'an itself: "There is no compulsion in religion. Truth stands out clearly from falsehood; whoever rejects evil and believes in God has grasped the most trustworthy hand-hold that never breaks. And God is All-Hearing and All-Knowing." (Qur'an 2:256)
The life, honor and property of all citizens in a Muslim society are considered sacred whether the person is Muslim or not. Racism and sexism are incomprehensible to Muslims, for the Qur'an speaks of human equality in the following terms:
"O mankind! We created you from a single soul, male and female, and made you into peoples and tribes, so that you may come to know one another. Truly, the most honored of you in God's sight is the greatest of you in piety. God is All-Knowing, All-Aware." (Qur'an 49:13)
