CHAPTER: The Time For the Subh (Fajr The Morning Prayer).
Aishah reported: The Messenger of Allah صلی اللہ علیہ وسلم would say the Fajr prayer after which the women would depart wrapped up their woolen garments, being unrecognizable because of the darkness before dawn.
Rafi bin Khadij reported the Messenger of Allah صلی اللہ علیہ وسلم as saying: Offer Fajr prayer at dawn, for it is most productive of rewards to you or most productive of reward.
