Ali bin Ali Rafai narrated that I heard Hasan (may Allah have mercy on him) say: The Jews did not leave any effort in troubling the Muslims. They used to say: O companions of Muhammad (peace be upon him)! By your Allah, it is only permissible for you to have intercourse with your wives from one side. He said: Upon this, Allah the Exalted revealed this verse: «﴿نِسَاؤُكُمْ حَرْثٌ لَكُمْ فَأْتُوا حَرْثَكُمْ أَنَّى شِئْتُمْ﴾» "Your wives are your fields; so approach your fields as you wish." [البقره 2: 223] In this way, Allah the Exalted fulfilled the needs of the believers.
