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.]
They wish that you should compromise (in religion out of courtesy) with them, so they (too) would compromise with you.
And obey not everyone who swears much, and is considered worthless,
A slanderer, going about with calumnies,
Hinderer of the good, transgressor, sinful,
Cruel, after all that base-born (of illegitimate birth),
(He was so) because he had wealth and children.
When Our Verses (of the Quran) are recited to him, he says:"Tales of the men of old!"
We shall brand him over the nose!
Verily, We have tried them as We tried the people of the garden, when they swore to pluck the fruits of the (garden) in the morning,
Without saying: Insha" Allah (If Allah will).
Then there passed by on the (garden) something (fire) from your Lord at night and burnt it while they were asleep.
So the (garden) became black by the morning, like a pitch dark night (in complete ruins).
