Hadith 16720
It is narrated from Sayyiduna Fakih bin Sa’d that the Prophet (peace and blessings be upon him) used to perform ghusl (ritual bath) with special care on the day of Jumu’ah, the day of ‘Arafah, the day of Eid al-Fitr, and the day of Eid al-Adha. Fakih bin Sa’d himself would also instruct his family members to perform ghusl on these days.
