The Messenger of Allah ﷺ would pray the dawn prayer, and the women would depart wrapped in their cloaks, unrecognizable due to the darkness.
إن كان رسول الله ﷺ ليصلي الصبح فينصرف النساء متلفعات بمروطهن ما يعرفن من الغلس.
Malik reported it in Waqut (4) from Yahya bin Saeed, from Amra bint Abdul-Rahman, from Ayesha, and mentioned the hadith. Bukhari transmitted it through his route in Adhan (867), and Muslim in Masajid (232/645). Both Bukhari and Muslim also narrated it through other routes from Ibn Shihab, from Urwa, from Ayesha, with similar wording, Bukhari (578, 372) and Muslim. Bukhari alone (872) narrated it through the route of Abdul-Rahman bin Qasim, from his father, from Ayesha, that the Messenger of Allah ﷺ used to pray in the darkness before dawn, and the believing women would leave without being recognized in the darkness, or without recognizing one another.Hafiz said, "Fa yansarifna" follows the dialect of Banu Harith, and likewise his saying "la yarifna baduhunna badan." This is in the narration of Hamawi and Kashmihani, while others have "la yaraf" in the singular, following the standard usage.As for his saying "mutalaffiat," Asmai said that talaffu means wrapping oneself in a garment until it envelops the body. In the commentary on Muwatta by Ibn Habib, it states that talaffu can only mean covering the head, while talafuf means either covering the head or leaving it uncovered.As for "al-murut," this is the plural of mirt, with the first letter vowelled with a kasrah, meaning a wrap made of silk, wool, or similar material. See Fath al-Bari (482/1).
