Musannaf Ibn Abi Shayba 3:45

Sufyan ibn 'Uyaynah narrated to us, from Isma'il ibn Muhammad, from al-A'raj, who said: I heard Abu Hurayrah saying: "Among you are those who say like this," and Sufyan raised his hands until he passed them beyond his head. "And among you are those who say like this," and Sufyan raised his hands until he passed them beyond his head. "And among you are those who say like this," and he placed his hands at his stomach. "And among you are those who say like this," meaning level with his shoulders.
