Y.S. Ya-Seen! (O Human being to whom this Divine Writ is revealed!)

The Wise Qur'an is a witness in itself that:

Surely, you are one of the Messengers.

On a straight path.

It is a revelation of the Almighty, the Merciful.

That you may warn a people whose ancestors were not warned, and are, therefore, unaware of what is right and what is wrong. [2:125, 7:158, 28:46, 32:3]

Already the word has come true for most of them, that they do not believe

Around their necks We (Our laws) have put shackles, reaching their chins so that they cannot bend their heads. Their heads are forced up in arrogance (like the agitated camel who keeps his head high refusing to drink the life- giving water).

And We have set a bar before them and a bar behind them, and thus have covered them so that they cannot see. [They neither look to the future nor derive any lesson from history]

Whether you warn them or warn them not, it is the same for them. [Their attitude bars them from attaining faith]
