Whatever benefit comes to you (O man!), it is from Allah, and whatever misfortune befalls you, it is from yourself, and We have sent you (O Prophet!), to mankind as a messenger; and Allah is sufficient as a witness.

O you who believe! be maintainers of justice, bearers of witness of Allah's sake, though it may be against your own selves or (your) parents or near relatives; if he be rich or poor, Allah is nearer to them both in compassion; therefore do not follow (your) low desires, lest you deviate; and if you swerve or turn aside, then surely Allah is aware of what you do.

Who is then more unjust than he who forges a lie against Allah or rejects His communications? (As for) those, their portion of the Book shall reach them, until when Our messengers come to them causing them to die, they shall say: Where is that which you used to call upon besides Allah? They would say: They are gone away from us; and they shall bear witness against themselves that they were unbelievers

The idolaters have no right to visit the mosques of Allah while bearing witness to unbelief against themselves, these it is whose doings are null, and in the fire shall they abide.

And (as for) those who accuse their wives and have no witnesses except themselves, the evidence of one of these (should be taken) four times, bearing Allah to witness that he is most surely of the truthful ones.
