Musannaf Ibn Abi Shayba 3:2292

Ibn Idris narrated to us, from Isma'il, from his father, who said: He used to pray behind Abu Hurayrah. He said: His prayer was similar to the prayer of Qays; he would perfect the bowing and the prostration, and he would be brief. He said: It was said to Abu Hurayrah, "Was the prayer of the Messenger of Allah (may Allah bless him and grant him peace) like this?" He said, "Yes, and even briefer."
