It is narrated from Sayyiduna Anas (may Allah be pleased with him) that he said: "When we raised our heads from bowing while praying behind the Prophet (peace and blessings be upon him), we would remain standing until we saw that the Prophet (peace and blessings be upon him) had gone into prostration and had placed his blessed face firmly on the ground; then we would prostrate after that."
And the hadith of Abd al-Aziz bin Rufay' from an elder of the Ansar (may Allah be pleased with him) will come later, if Allah Almighty wills, in the chapter on the description of the prayer.
