Musnad Ahmad 37:7

He said: Ya'qub narrated to us, 'Abd al-Malik ibn al-Rabi' ibn Sabrah narrated to us, from his father, from his grandfather, that he said: "The Messenger of Allah, may Allah bless him and grant him peace, forbade us from praying in the resting places of camels, and he granted a concession for us to pray in the enclosures of sheep." "And the Messenger of Allah, may Allah bless him and grant him peace, forbade temporary marriage (mut'ah)."
