Al-Qalam

Nun. [These letters (Nun, etc.) are one of the miracles of the Quran, and none but Allah (Alone) knows their meanings]. By the pen and what the (angels) write (in the Records of men).

You (O Muhammad SAW) are not, by the Grace of your Lord, a madman.

And verily, for you (O Muhammad SAW) will be an endless reward.

And verily, you (O Muhammad SAW) are on an exalted standard of character.

You will see, and they will see,

Which of you is afflicted with madness.

Verily, your Lord knows better, who (among men) has gone astray from His Path, and He knows better those who are guided.

So (O Muhammad SAW) obey not the deniers [(of Islamic Monotheism those who belie the Verses of Allah), the Oneness of Allah, and the Messenger of Allah (Muhammad SAW), etc.]
