Say: Who is the Lord of the heavens and the earth?-- Say: Allah. Say: Do you take then besides Him guardians who do not control any profit or harm for themselves? Say: Are the blind and the seeing alike? Or can the darkness and the light be equal? Or have they set up with Allah associates who have created creation like His, so that what is created became confused to them? Say: Allah is the Creator of all things, and He is the One, the Supreme.

And do not kill any one whom Allah has forbidden, except for a just cause, and whoever is slain unjustly, We have indeed given to his heir authority, so let him not exceed the just limits in slaying; surely he is aided.
