A Book revealed unto thee (Muhammad SAW),- So let thy heart be oppressed no more by any difficulty on that account,- that with it thou mightest warn (the erring) and teach the Believers).
Follow (O men!) the revelation given unto you from your Lord, and follow not, as friends or protectors, other than Him. Little it is ye remember of admonition.
How many towns have We destroyed (for their sins)? Our punishment took them on a sudden by night or while they slept for their afternoon rest.
When (thus) Our punishment took them, no cry did they utter but this: “Indeed we did wrong.”

And verily, We shall recount their whole story with knowledge, for We were never absent (at any time or place).
Ignorance is a difference
