‘Nun. [These letters (Nun, etc.) are one of the miracles of the Qur’an, and none but Allah (Alone) knows their meanings]. By the pen and by what they (the angels) write (in the Records of men). {1}
You (O Muhammad صلى الله عليه وسلم), by the Grace of your Lord, are not mad. {2}
And Verily, for you (O Muhammad صلى الله عليه وسلم) will be an endless reward. {3}
And Verily, you (O Muhammad صلى الله عليه وسلم) are on an exalted (standard of) character. {4}
You will see, and they will see, {5}
Which of you is afflicted with madness. {6}
Verily, your Lord is the Best Knower of him who has gone astray from His Path, and He is the Best Knower of those who are guided. {7}
[Qur’an, chapter 68: verses 1-7, English interpretation of Arabic]
