Sayyiduna Ibn Abbas and Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both) both said that there was no adhan on the day of Eid al-Fitr or the day of Eid al-Adha. Then, after some time, I asked him about it, and he said: Sayyiduna Jabir bin Abdullah al-Ansari (may Allah be pleased with him) informed me that on the day of Eid al-Fitr, when the imam comes out and after he comes out, there is no adhan and no iqamah.
