Silsilah as-Sahihah 535 — Following the Imam

It is narrated from Sayyiduna Samurah bin Jundub (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) said: "When you stand to perform prayer (following an imam), do not precede the imam in bowing and prostrating; rather, he will precede you."
