(Imām Bukhārī narrates): Abul Yaman narrated the hadeeth to us, he said: Shu'aib informed us, from Az-Zuhri, he said: Ali bin Husain narrated the hadeeth to me, from Al-Musawwar bin Makhramah, he said that

the Messenger of Allāh صلى الله عليه وسلم stood up, so when he recited the kalimah of shahadah, I heard him saying: "Amma ba'd" (after the shahadah).

Zubaidi has corroborated Shu'aib, from Az-Zuhri.
