It is narrated from Sayyiduna Mu'adh bin Jabal (may Allah be pleased with him) that he went to Syria and saw the Christians prostrating to their bishops, priests and patriarchs, and he saw the Jews prostrating to their rabbis, their scholars of the Torah, their learned men and their jurists. He said (to them): "Why do you do this?" They replied: "This is the greeting (form of salutation) of the Prophets (peace be upon them)." Sayyiduna Mu'adh (may Allah be pleased with him) said: "Then we are more entitled to do this with our Prophet (peace and blessings be upon him)." So the Prophet (peace and blessings be upon him) said: "They have lied against their Prophets just as they distorted their Book. If I were to command anyone to prostrate to anyone, I would have commanded the woman to prostrate to her husband, because of his great right over her. And no woman can find the sweetness of faith until she fulfils the right of her husband, such that even if her husband asks her for herself while she is on a camel's saddle, she should not refuse." Imam al-Hakim said that this hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it.
