The word(s) "pen" appears 244 time(s) in 213 verse(s) in Quran in Muhammad Pickthal translation.

(141) These will be given their reward twice over, because they are steadfast and repel evil with good, and spend of that wherewith We have provided them,

(142) But as for him who shall repent and believe and do right, he haply may be one of the successful.

(143) And whosoever striveth, striveth only for himself, for lo! Allah is altogether Independent of (His) creatures.

(144) And when harm toucheth men they cry unto their Lord, turning to Him in repentance; then, when they have tasted of His mercy, behold! some of them attribute partners to their Lord

(145) But if they strive with thee to make thee ascribe unto Me as partner that of which thou hast no knowledge, then obey them not. Consort with them in the world kindly, and follow the path of him who repenteth unto Me. Then unto Me will be your return, and I shall tell you what ye used to do -

(146) And if all the trees in the earth were pens, and the sea, with seven more seas to help it, (were ink), the words of Allah could not be exhausted. Lo! Allah is Mighty, Wise.

(147) Who forsake their beds to cry unto their Lord in fear and hope, and spend of that We have bestowed on them.

(148) And when a party of them said: O folk of Yathrib! There is no stand (possible) for you, therefor turn back. And certain of them (even) sought permission of the Prophet, saying: Our homes lie open (to the enemy). And they lay not open. They but wished to flee.

(149) Their salutation on the day when they shall meet Him will be: Peace. And He hath prepared for them a goodly recompense.

(150) Have they not observed what is before them and what is behind them of the sky and the earth? If We will, We can make the earth swallow them, or cause obliteration from the sky to fall on them. Lo! herein surely is a portent for every slave who turneth (to Allah) repentant.
