Musnad Ahmad 957:1

Isma'il ibn Muhammad—who is Abu Ibrahim al-Mu'aqqib—narrated to us, Marwan—meaning Ibn Mu'awiyah al-Fazari—narrated to us, Mansur ibn Hayyan al-Asadi narrated to us, from Sulayman ibn Bishr al-Khuza'i, from his maternal uncle Malik ibn 'Abd Allah, who said: "I went on a military expedition with the Messenger of Allah, peace and blessings of Allah be upon him, and I never prayed behind an Imam who was more concise in prayer than him, while [still] completing the bowing and prostration."
