The word(s) "pen" appears 209 time(s) in 182 verse(s) in Quran in Muhammad Habib Shakir translation.

(131) So he cast down his rod, and lo! it was an obvious serpent,

(132) And cast down your staff. So when he saw it in motion as if it were a serpent, he turned back retreating and did not return: O Musa! fear not; surely the apostles shall not fear in My presence;

(133) And enter your hand into the opening of your bosom, it shall come forth white without evil; among nine signs to Firon and his people, surely they are a transgressing people.

(134) And he went into the city at a time of unvigilance on the part of its people, so he found therein two men fighting, one being of his party and the other of his foes, and he who was of his party cried out to him for help against him who was of his enemies, so Musa struck him with his fist and killed him. He said: This is on account of the Shaitan's doing; surely he is an enemy, openly leading astray.

(135) And saying: Cast down you staff. So when he saw it in motion as if it were a serpent, he turned back retreating, and did not return. O Musa! come forward and fear not; surely you are of those who are secure;

(136) Enter your hand into the opening of your bosom, it will come forth white without evil, and draw your hand to yourself to ward off fear: so these two shall be two arguments from your Lord to Firon and his chiefs, surely they are a transgressing people.

(137) These shall be granted their reward twice, because they are steadfast and they repel evil with good and spend out of what We have given them.

(138) But as to him who repents and believes and does good, maybe he will be among the successful:

(139) And were every tree that is in the earth (made into) pens and the sea (to supply it with ink), with seven more seas to increase it, the words of Allah would not come to an end; surely Allah is Mighty, Wise.

(140) Their sides draw away from (their) beds, they call upon their Lord in fear and in hope, and they spend (benevolently) out of what We have given them.
