Abu Yunus, the freed slave of 'Aishah said: 'Aishah commanded me to write for her come passage from the Qur'an. She also added: When you reach the following verse, inform me: "Be guardian of your prayers and of the midmost prayer" (2:238). When I reached it, I informed her. She asked me to write: "Be guardians of your prayers, and of the midmost prayer, and of the 'Asr prayer, and stand up with devotion of Allah" (2:238). 'Aishah then said: I heard it from the Messenger of Allah (PBUH). Translation Not Available
