Sayyiduna Abu Ayyub al-Ansari (may Allah be pleased with him) says: The Messenger of Allah (peace and blessings be upon him) said: "O Muslims! Whoever of you comes to the Friday prayer, let him take a ritual bath (ghusl); and if he finds perfume, there is no harm in his applying some of it; and hold fast to this tooth-stick (siwak)." Ata bin Yazid says: Then Ibn Abbas (may Allah be pleased with them both) narrated to me the same thing that Abu Ayyub (may Allah be pleased with him) had narrated to me, and Abdullah (bin Abbas) said: "As for the ritual bath, yes, that is correct; but as for perfume, I do not know."
