Chapter: It is recommended to pray Subh early, at the beginning of its time, when it is still dark; and the length of recitation therein
A'isha reported: The Messenger of Allah ( صلی اللہ علیہ وسلم ) 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.)
