سورة المزمل

Ali ibn Ibrahim (may Allah have mercy on him): يَا أَیُّهَا الْمُزَّمِّلُ [O you who have wrapped up in your garments!] refers to the Prophet (peace be upon him and his family) himself, who used to wrap his garment around himself and sleep.

Imam Sadiq (peace be upon him): Kalbi said: Imam Sadiq (peace be upon him) said to me: "How many names does Muhammad (peace be upon him and his family) have in the Quran?" I said: "Two or three names." He said: "O Kalbi! He has ten names... [among them]: ... یَا أَیُّهَا الْمُزَّمِّلُ [O you who have wrapped up in your garments!] and یَا أَیُّهَا الْمُدَّثِّرُ [O you who are covered up!] and قَدْ أَنْزَلَ اللهُ إِلَیْکُمْ ذِکْراً* رَسُولًا [Allah has already sent down to you a reminder, a messenger] (Talaq/10)."

The Messenger of Allah (peace be upon him and his family): It is narrated that the Prophet (peace be upon him and his family) entered upon Khadija (peace be upon her) and said: "Cover me in a garment." While he was in that state, Jibrail (peace be upon him) called out to him: یَا أَیُّهَا الْمُزَّمِّلُ [O you who have wrapped up in your garments!].

Ali ibn Ibrahim (may Allah have mercy on him): It is the Prophet (peace be upon him and his family) himself, who used to wrap himself in his garment and sleep. So Allah the Mighty and Majestic said: يَا أَيُّهَا الْمُزَّمِّلُ * قُمِ اللَّيْلَ إِلَّا قَلِيلًا [O you who have wrapped up in your garments! Rise to pray in the night except a little].
