It was narrated from Ibn ‘Abbas (رضي الله عنه) that

The Messenger of Allah (ﷺ) went out on the day of Adha - or the day of Fitr, but I think it most likely that he said: the day of Fitr - and prayed two rak'ahs, with no prayer before or after them. Then he went to the women, accompanied by Bilal, and enjoined them to give charity, and they started throwing their earrings and necklaces.
