Abu Humaid Al-Sa'idi

Abu Humaid al-Sa'idi, may Allah be pleased with him, was a companion of the Prophet ﷺ from the Sa'ida clan of the Ansar of Medina. He is one of the most important narrators of the physical description of the Prophet's ﷺ prayer. He is particularly known for a detailed and famous narration in which he described the Prophet's ﷺ prayer in precise, step-by-step terms before ten of the companions — including Abu Qatada — all of whom confirmed that he had described it most accurately. This narration enumerates the specific postures and actions of the Prophet ﷺ from the opening takbir through each rukn: the raising of hands, the placement of hands on knees in ruku', the straightening of the back, the positions in sujud, and the manner of sitting in tashahhud. It became one of the most cited narrations in all books of Islamic jurisprudence dealing with the description of salah. Scholars of all four madhabs cited it as primary evidence for the physical details of prayer. His narrations are preserved in Sunan Abu Dawud, Sunan al-Tirmidhi, and Ibn Majah, and are considered foundational texts for the chapter on prayer.
