Musnad Ahmad

It is narrated from Hazrat Ibn Abi Awfa (may Allah be pleased with him) that when Hazrat Mu'adh (may Allah be pleased with him) reached Yemen, he saw that the Christians there prostrated before their priests and religious leaders. It occurred to his heart that the Prophet Muhammad (peace and blessings be upon him) is even more deserving of such reverence. Therefore, after returning from Yemen, he submitted, "O Messenger of Allah! I saw the Christians prostrating before their priests and religious leaders. It comes to my heart that you are more deserving of such reverence than them." The Prophet Muhammad (peace and blessings be upon him) said, "If I were to command anyone to prostrate before another, I would have commanded a woman to prostrate before her husband. And no woman can fully fulfill the rights of Allah until she fully fulfills the rights of her husband, even if the man desires to fulfill his wish from her while she is baking bread on the stove, she should fulfill his wish."

The previous hadith is also narrated through this second chain, but with this addition: "I asked those people, 'Why do you do this?' They said, 'This was the way of honoring the prophets (peace be upon them) before us.' I said, 'Then we are more entitled to do this with our Prophet Muhammad (peace and blessings be upon him).' The Prophet Muhammad (peace and blessings be upon him) said, 'Just as they altered their books, they also lied about their prophets. Allah Almighty has given us something better in its place, that is, Salam (greeting of peace), which is the way of honoring among the people of Paradise.'"
