Surah 40: Surat ul Momin - سورة مومن - (The Forgiver)

And He shows you His signs. So which of the signs of Allah do you deny?

Have they not traveled through the land and observed how was the end of those before them? They were more numerous than themselves and greater in strength and in impression on the land, but they were not availed by what they used to earn.

And when their messengers came to them with clear proofs, they [merely] rejoiced in what they had of knowledge, but they were enveloped by what they used to ridicule.

And when they saw Our punishment, they said," We believe in Allah alone and disbelieve in that which we used to associate with Him."

But never did their faith benefit them once they saw Our punishment. [It is] the established way of Allah which has preceded among His servants. And the disbelievers thereupon lost [all].
