Musannaf Ibn Abi Shaybah

Kurdoos narrates that Hazrat Saeed bin Aas, at the beginning of the month of Dhul-Hijjah, called Hazrat Abdullah, Hazrat Hudhaifa (may Allah be pleased with him), Hazrat Abu Masood Ansari, and Hazrat Abu Musa Ashari and asked them about the Takbeerat of Eid. All of them entrusted this matter to Hazrat Abdullah, so he said: Say Takbeer while standing, then say Takbeer, then say Takbeer, then after saying Takbeer, recite (Qira'at), then say Takbeer and go into Ruku, then in the next Rak'ah, after standing up, recite (Qira'at), then say Takbeer, then say Takbeer, then say Takbeer, then after saying Takbeer, go into Ruku.
