Sahih Muslim Book 4, Hadith Number 1347.

Chapter : Time for the night prayer and its delay.

‘Aisha reported: The Messenger of Allah (may peace be upon him) used to observe the morning prayer, and the women would go back wrapped in their mantles being unrecognisable because of the darkness before dawn. (Ishaq b. Musa) al-Ansari (one of the transmitters in this chain of narration) narrated “wrapped” (only) in his narration. (No mention was made of mantles.)
