How does Islam guarantee human rights?
Freedom of conscience is laid down by the Quran itself: 'There is no compulsion in religion'. (2:256)
The life and property of all citizens in an Islamic state are considered sacred whether a person is Muslim or not.
Racism is incomprehensible to Muslims, for the Quran speaks of human equality in the following terms:
O mankind! We created you from a single soul, male and female, and made you into nations 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 (49-13)
