Musannaf Ibn Abi Shayba 3:2621

Hushaym narrated to us, he said: Yazid ibn Abi Ziyad informed us, from Ubayd Allah ibn al-Harith, who said: I was with Sa’d, and a son of his came. He said to him, "Have you performed ghusl (ritual bath)?" He said, "No, I performed wudu (ablution), then I came." Sa’d said to him, "I did not think that anyone would leave the ghusl on the day of Jumu’ah."
