Sunan an-Nasa'i 1312

Ahmad ibn Sulayman informed us: Yahya ibn Adam narrated to us: Malik—who is Ibn Mighwal—narrated to us, from Talhah ibn Musarrif, from Zayd ibn Wahb, from Hudhayfah, who saw a man praying carelessly. Hudhayfah asked him, “How long have you been praying this prayer?” He said, “For forty years.” Hudhayfah said, “You have not truly prayed for forty years. If you were to die while praying in this manner, you would die following a way other than the way of Muhammad (ﷺ).” Then he said: “A person can make his prayer brief while still completing it and performing it well.”
