Those who consume interest cannot stand [on the Day of Resurrection] except as one stands who is being beaten by Satan into insanity. That is because they say, "Trade is [just] like interest." But Allah has permitted trade and has forbidden interest. So whoever has received an admonition from his Lord and desists may have what is past, and his affair rests with Allah . But whoever returns to [dealing in interest or usury] - those are the companions of the Fire; they will abide eternally therein.

Then do they not give thought? There is in their companion [Muhammad] no madness. He is not but a clear warner.

We only say that some of our gods have possessed you with evil." He said, "Indeed, I call Allah to witness, and witness [yourselves] that I am free from whatever you associate with Allah

And they say,"O you upon whom the message has been sent down, indeed you are mad.

[Pharaoh] said, "Indeed, your 'messenger' who has been sent to you is mad."

And were saying, "Are we to leave our gods for a mad poet?"

Then they turned away from him and said, "[He was] taught [and is] a madman."

But he turned away with his supporters and said," A magician or a madman."

Similarly, there came not to those before them any messenger except that they said, "A magician or a madman."

So remind [O Muhammad], for you are not, by the favor of your Lord, a soothsayer or a madman.
