??? ???? ?? ?????? - A Magic Pen in my Pencil case

وَجَدَ كَريم قَلَمًا مُزَخْرَفًا في مِحْفَظَتِه. سَألَ أصْدِقاءَه، إلّا أنَّ أحَدًا مِنْهُمْ لَمْ يَعْرِفْ مَنْ يَكونُ صاحِبُ القَلَم.

"Karim" finds a pen with a lovely pattern in his pencil case. He asks his friends about it, but none of them identify the owner of this pen. Many incidents will elapse, until "Karim" will discover that there is a funny story about this pen.
