Zaid b. Thabit said: The Messenger of Allah (PBUH) used to offer the Zuhr prayer in midday heat; and no prayer was harder on the Companions of the Messenger of Allah (PBUH) 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.
