Sayyiduna Muawiyah bin Abu Sufyan (may Allah be pleased with him) narrates: The Noble Prophet (peace and blessings be upon him) said: "Do not try to go into ruku‘ (bowing) or sujood (prostration) before me, because for as long as I go into ruku‘ before you, you will find me in that state when you reach it, and for as long as I go into sujood before you, you will find me in that state when I raise my head. The reason for this is that my weight has increased."
