It is narrated from Sayyiduna Mu'adh bin Jabal (may Allah be pleased with him), he says: When I returned from Yemen, I said: O Messenger of Allah! I saw in Yemen that people prostrate to one another, so should we not prostrate to you as well? The Prophet (peace and blessings be upon him) said: If I were to permit a human to prostrate to another human, I would have ordered the wife to prostrate to her husband.
