Al-Qalam القلم "The Pen"

The Pen (القلم, al-qalam) is the sixty-eighth chapter of the Qur'an with 52 verses

Quran:68 describes God's justice and the judgment day.

Three notable themes of this Surah are its response to the opponents' objections, warning and admonition to the disbelievers, and exhortation of patience to the Islamic prophet Muhammad.[1] Chronologically, this was the first appearance of any of the "disjointed" [i.e., single] letters (muqattaat) which precede a number of the surahs of the Qur'an,[2] while in Quranic order this is the last surah to have the appearance of muqattaat.[3]
