al-Muzammil (Arabic: المزمل‎, “The Enshrouded One”, “Bundled Up”, “Enfolded”) is the seventy-third chapter (surah) of the Qur'an, containing 20 verses (ayat), which are recognized by Muslims as the word of God (Allah).

Al-Muzzammil takes its name from the reference to prophet Muhammad, in his cloak praying at night, in the opening verses of the chapter. Many commentators claim that “The Enfolded One” is a name for Muhammad, used throughout the Koran (Mushaf).

In the beginning of this surah, God prepares Muhammad for an important revelation. In preparation for this revelation, God loosens the strict regulation on night prayer. Muhammad is then instructed to be patient for the disbelievers will be punished in Hell, as exemplified by a story of Pharaoh's punishment.

Placement and coherence with other surahs
The idea of textual relation between the verses of a chapter has been discussed under various titles such as nazm and munasabah in non-English literature and coherence, text relations, intertextuality, and unity in English literature. Hamiduddin Farahi, an Islamic scholar of the Indian subcontinent, is known for his work on the concept of nazm, or coherence, in the Quran. Fakhruddin al-Razi (died 1209 CE), Zarkashi (died 1392) and several other classical as well as contemporary Quranic scholars have contributed to the studies.[10] This surah belongs to the last (7th) group of surahs which starts from Surah Al-Mulk (67) and runs till the end of the Quran.
