Sunan Abi Dawud 853
سنن أبي داود#853SahihAnas b. Malik said:I did not offer prayer behind anyone more brief than the one offered by the Messenger of Allah(ﷺ) and that was perfect. When the Messenger of Allah(ﷺ) said: “Allah listens to him who praises Him,” he stood long we thought that he had omitted something; then he say takbir(Allah is most great) and prostrate, and would sit between the two prostrations so long that we thought that he had omitted something
