Musannaf Ibn Abi Shayba 3:2091

Yazid ibn Harun narrated to us, from Ash'ath, from al-Sha'bi, from Sa'd and Ammar, that they prayed three [rak'ahs]. It was said to them [about that], so they performed the one that remained for them, then they performed the taslim. Then they said the takbir, then they prostrated, then they said the takbir, then they raised [their heads], then they said the takbir and prostrated, then they said the takbir and raised [their heads].
