al-Muzzammil (Arabic: المزمل‎, “The Enshrouded One”, “Bundled Up”, “Enfolded”) is the seventy-third chapter (sūrah) of the Qur'an, containing 20 verses (āyāt), 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 Qur'an.[1]

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.
