Yazid bin Khumayr (may Allah have mercy on him) said: Abdullah bin Busr (may Allah be pleased with him) went out with the people on the day of Eid al-Fitr or Eid al-Adha, and he disapproved of the imam's delay and said: "With the Prophet (peace and blessings be upon him) we would have finished by this time, and that was the time of the voluntary prayers."
