Narrated by ‘Abullah bin Abi Awfa: Allah’s Apostle Said, “Had I ordered a person to prostrate to someone rather than Allah, I would have ordered the wife to prostrate to her husband. By Allah, who holds the soul of Muhammad in his hands, the wife will not be fulfilling her duty towards Allah until she fulfils her duty towards her husband. If he asks her (for sexual intercourse) while she is on a camel , she should not disobey him.”
