It is Sunnah for a Muslim to take a bath before the Eid prayer, and he follows the description of the washing of the Messenger of God - may God bless him and grant him peace -, on the authority of Aisha, the mother of the believers: (The Messenger of God, may God’s prayers and peace be upon him, if he washed from impurity, washed his hands, and performed ablution as he did for prayer, then He took a bath, then plucked it with his hand his hair, so that when he thought that he had irrigated his skin, he poured water over it three times, then washed the rest of his body).
There were many opinions of jurists at the time of Eid washing; It is sufficient for the Shaafa'is to take a bath for the feast before dawn; Because among the people who go out to the Eid prayer place from far away, and his time enters according to the Malikis by entering the last sixth of the night, and washing after the morning prayer is better for them, and it is according to the Hanbalis after dawn, so it is not sufficient to wash before dawn, and the Hanafis did not elaborate on that.
