Al-Matalib al-'Aliyah 753 — The two Eid prayers

Muhammad bin Ishaq narrates from Nafi' that he asked him how Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) used to perform (the prayer and other practices of) the day of Eid. He said: "He would attend the Fajr prayer with the Imam, then return to his house and take a (complete) bath like the ritual bath (ghusl) for major impurity, put on his finest clothes and use the best perfume he had. Then he would leave the house until he reached the Eid prayer ground, and sit there until the Imam arrived. When the Imam came, he would perform the Eid prayer with him. Then on the way back he would enter the mosque of the Messenger of Allah (peace and blessings be upon him) (the Prophet's Mosque) and pray two rak'ahs in it, then go to his house."
[Musnad al-Harith: 753]. The chain of this report is hasan (good), and this practice of Ibn Umar (may Allah be pleased with them both) is authentic as a sunnah of the Companions.
