Musnad Ahmad 658:21

Hushaym narrated to us, from Yazid ibn Abi Ziyad, from Abd al-Rahman ibn Abi Layla, from al-Bara’ ibn Azib, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "Indeed, it is a duty upon the Muslims that one of them should perform ghusl (full ablution) on the day of Jumu'ah. And that he should touch some perfume if his family has any. If they do not have any perfume, then water is perfume."
