It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that on the day of Eid al-Fitr the Messenger of Allah (peace and blessings be upon him) would say the takbir from the time he left his house until he reached the Eid prayer ground. This hadith is gharib (singular) in both its chain and its text, because the two Shaykhs (Bukhari and Muslim) did not use al-Walid bin Muhammad al-Muwaqqari or Musa bin Ata al-Balqawi as evidence; however, it is a Sunnah current among the leading scholars of hadith, and it is established through sahih (authentic) narrations from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) and other Companions:

It is narrated about Sayyiduna Ibn Umar (may Allah be pleased with them both) that on the two Eids he would go out from the mosque and keep saying the takbir until he reached the Eid prayer ground.

Abu Abd al-Rahman al-Sulami narrates that the Companions gave more attention and intensity to saying the takbir on Eid al-Fitr than on Eid al-Adha.
