Hadith 2226
Sayyiduna Bara’ (may Allah be pleased with him) narrates: And he did not speak falsely. He says, when the Companions (may Allah be pleased with them) used to pray with the Prophet (peace and blessings of Allah be upon him), after raising their heads from bowing (ruku‘), they would remain standing, until when they saw that he had gone into prostration, then they would also go into prostration.
