'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 (ﷺ).

The Messenger of Allah (ﷺ) used to offer the Zuhr prayer in midday heat; and no prayer was harder on the Companions of the Messenger of Allah (ﷺ) that this one. Hence the revelation came down: Be guardians of your prayers, and of the midmost prayer (2:238). He (the narrator) said: There are two prayers before it and two prayers after it.
