Musnad Ahmad 3983

Translation

✧ The Messenger of God ﷺ prayed five [rakʿahs]—the noon or afternoon prayer. When he finished, it was said to him: “O Messenger of God, has something been added to the prayer?” He said: “No.” They said: “You prayed five.” He prostrated the two prostrations of forgetfulness and said: “I am only a human being; I remember as you remember and forget as you forget.”
