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 We have placed coverings on their hearts and a heaviness in their ears lest they understand it, and when you mention your Lord alone in the Quran they turn their backs in aversion.

And if Allah had pleased He would surely have made them a single community, but He makes whom He pleases enter into His mercy, and the unjust it is that shall have no guardian or helper.
