Musannaf Ibn Abi Shayba 3:2646

Hushaym narrated to us, he said: Isma'il informed us from al-Sha'bi, and 'Ubaydah and Mughirah informed us from Ibrahim, and 'Abd al-Malik from 'Ata', that they said: Whoever performs wudu' on the day of Jumu'ah, then it is good; and whoever performs ghusl, then the ghusl is better.
