It is narrated from Sayyiduna Muawiyah bin Abi Sufyan (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: Do not precede me in bowing (ruku‘) and prostration (sujud). If I precede you in bowing, you will catch up with me when I rise; similarly, if I precede you in prostration, you will catch up with me when I rise. Indeed, now I have become old.
