Ibn 'Abbas and Jaibir b. 'Abdullah al-Ansari reported:
There was no Adhan on the (occasion) of Id-ul-Fitr and Id-ul-Adha. I (Ibn Juraij) said: I asked him after some time about it. He ('Ata', one of the narrators) said: Jabir b. 'Abdullah al-Ansari told me: There is neither any Adhan on Id-ul-Fitr when the Imam comes out, nor even after his coming out; their is neither lqama nor call nor anything of the sort of calling on that day and nor Iqama.
