Musannaf Ibn Abi Shayba 9:1165

Yunus ibn Muhammad narrated to us, from Abd al-Wahid ibn Ziyad, who said: Abu al-Umays narrated to us, from Iyas ibn Salamah, from his father, who said: The Messenger of Allah (may Allah bless him and grant him peace) granted a concession for temporary marriage (mut'ah) for three days during the year of Awtas, then he forbade it.
