Do not kill any person the life of whom is sanctified by Allah, except for a just reason.(Just reasons like the death penalty given to rapists in the Islamic law) And whoever is killed unjustly, We have invested his heir with authority, but he must not cross the limit in the matter of killing.Surely, he will be helped.(33)
[The Noble Qur'an Ch.17 - Verse 33]
O mankind! We created you from a single (pair) of a male and a female, and made you into nations and tribes, that ye may know each other (not that ye may despise each other). Verily the most honoured of you in the sight of Allah is (he or she who is) the most righteous of you. And Allah has full knowledge and is well acquainted (with all things). (13)
[The Noble Qur'an Ch.49 - Verse 13 ]
Allah enjoins to do justice and to adopt good behavior and to give relatives (their due rights), and forbids shameful acts, evil deeds and oppressive attitude. He exhorts you, so that you may be mindful.
[The Noble Qur'an Ch.16 - Verse 19 ]
