The word(s) "pen" appears 516 time(s) in 454 verse(s) in Quran in Abdullah Yusuf Ali translation.

(341) But those who dispute concerning Allah after He has been accepted,- futile is their dispute in the Sight of their Lord: on them will be a penalty terrible.

(342) What! have they partners (in godhead), who have established for them some religion without the permission of Allah? Had it not been for the Decree of Judgment, the matter would have been decided between them (at once). But verily the Wrong-doers will have a grievous penalty.

(343) He is the One that accepts repentance from His Servants and forgives sins: and He knows all that ye do.

(344) And He listens to those who believe and do deeds of righteousness, and gives them increase of His Bounty: but for the Unbelievers their is a terrible penalty.

(345) Whatever misfortune happens to you, is because of the things your hands have wrought, and for many (of them) He grants forgiveness.

(346) Those who hearken to their Lord, and establish regular Prayer; who (conduct) their affairs by mutual Consultation; who spend out of what We bestow on them for Sustenance;

(347) The recompense for an injury is an injury equal thereto (in degree): but if a person forgives and makes reconciliation, his reward is due from Allah: for (Allah) loveth not those who do wrong.

(348) The blame is only against those who oppress men and wrong-doing and insolently transgress beyond bounds through the land, defying right and justice: for such there will be a penalty grievous.

(349) For any whom Allah leaves astray, there is no protector thereafter. And thou wilt see the Wrong-doers, when in sight of the penalty, Say: "Is there any way (to effect) a return?"

(350) And thou wilt see them brought forward to the (penalty), in a humble frame of mind because of (their) disgrace, (and) looking with a stealthy glance. And the Believers will say: "Those are indeed in loss, who have given to perdition their own selves and those belonging to them on the Day of Judgment. Behold! Truly the Wrong-doers are in a lasting penalty!"
