Musnad Ahmad 25:331

Abdullah ibn Yazid narrated to us, from Dawud—meaning Ibn Abi al-Furat—from Ibrahim, from ‘Ata’, from Ibn ‘Abbas, who said: "The Prophet of Allah (may Allah bless him and grant him peace) prayed two rak'ahs with the people on the day of Fitr without an adhan or an iqamah. Then he delivered a sermon after the prayer. Then he took the hand of Bilal and went to the women and preached to them. Then, after he had finished with them, he ordered Bilal to go to them and command them to give charity."
