سنن أبي داود

‘Abd al Rahman b. Abza said that he offered prayer along with the Messenger of Allah(ﷺ) but he did not complete the takbir.

Abu Dawud said: This means that when he raised his head after bowing and when he was about to prostrate, he did not utter the takbir, and when he stood up after prostration, he did not utter the takbir.
