'There is no compulsion in religion'.
Al-Quran 2:256

The life and property of all citizens in an Islamic state are considered sacred. Racism is incomprehensible to Muslims, the Qur'an speaks of human equality as follows:

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 honoured of you in God's sight is the greatest of you in piety. God is All-Knowing, All-Aware. Al-Quran 49:13
