Musannaf Ibn Abi Shayba 3:3011

Hushaym narrated to us, he said: Abu al-Miqdam, the freed slave of Quraysh, informed us, from al-Qasim ibn Muhammad: That he bought something from a man on the day of Friday. Then he met him after that and said: "Release me from the sale, for I think I bought from you what I bought after the sun had passed its zenith."
