Bukhari narrated it in the Book of Adhan (706), and Muslim in the Book of Prayer (469), both through Abdul-Aziz bin Suhayb, from Anas, as mentioned above, with the wording being Bukhari's. Muslim's wording is, "He used to shorten the prayer while completing it."He also narrated it through Qatada, from Anas, who said, "The Messenger of Allah ﷺ was among the lightest of people in prayer while still completing it fully."What is meant by shortening while completing is performing the essential elements and the recommended parts with the least amount possible.
