Silsilat al-Ahadith al-Sahihah

It is narrated from Sayyiduna Zaid bin Arqam (may Allah be pleased with him) that Sayyiduna Mu'adh (may Allah be pleased with him) said: O Messenger of Allah! You must have seen that the People of the Book prostrate to their priests and scholars. Can we also prostrate to you? The Prophet (peace and blessings of Allah be upon him) said: "If I were to command anyone to prostrate to another, I would have commanded a woman to prostrate to her husband. And a wife cannot fulfill the right of her husband until it is such that if he asks her for himself and she is on a saddle, she does not refuse him."
