Sayyiduna Ibn Abbas (may Allah be pleased with them both) narrates that I was present on the occasion of Eid with the Prophet (peace and blessings of Allah be upon him), and with 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.
