Maliks Muwatta Book 10, Hadith Number 1.

Section : The Ghusl of the Two Ids, the Call to Prayer for Them, and the Iqama.

Yahya related to me from Malik that he had heard more than one of their men of knowledge say, “There has been no call to prayer or iqama for the id al-Fitr or the id al-Adha since the time of the Messenger of Allah, may Allah bless him and grant him peace.”

Malik said, “That is the sunna about which there is no disagreement among us.”
