Sayyiduna Ibn Abbas (may Allah be pleased with them both) narrates that on the occasion of Eid, the Prophet (peace and blessings be upon him), Sayyiduna Abu Bakr, Sayyiduna Umar, and Sayyiduna Uthman (may Allah be pleased with them all), all of them used to lead the prayer before the sermon without any call to prayer (adhan) or iqamah.
