Sunan Abi Dawud Book 2, Hadith 349
Maymun al-Makki said: that he saw Abdullah ibn az-Zubayr leading in prayer. He pointed with his hands (i.e. raised his hands opposite to the shoulders) when he stood up, when he bowed and when he prostrated, and when he got up after prostration, he pointed with his hands (i.e. raised his hands).
The I went to Ibn Abbas and said (to him) I saw Ibn az-Zubayr praying that I never saw anyone praying. I then told him about the pointing with his hands (raising his hands). He said: If you like to see the prayer of the Messenger of Allah (ﷺ) follower the prayer as offered by Abdullah ibn az-Zubayr.
When the Messenger of Allah (ﷺ) uttered the takbir (Allah is most great) for prayer (in the beginning), he raised his hands opposite to his shoulders; and when he bowed, he did like that; and when he raised his head to prostrate, he did like that; and when he got up at the end of two rak'ahs, he did like that.
Nadr ibn Kathir as-Sa'di said: Abdullah ibn Tawus prayed at my side in the mosque of al-Khayf. When he made the first prostration, he raised his head after it and raised his hands opposite to his face. This came as something strange for me. I, therefore, said it to Wuhayb ibn Khalid.
Then Wuhayb ibn Khalid said to him: You are doing a thing that I did not see anyone do. Ibn Tawus then replied: I saw my father doing it, and my father said: I saw Ibn Abbas doing it. I do not know but he said: The Prophet (ﷺ) used to do it.
