It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that this verse: «﴿نِسَاؤُكُمْ حَرْثٌ لَكُمْ﴾ [البقرة : 223]» "Your wives are a place of sowing of seed for you," was revealed regarding some Ansari people who came to the Prophet (peace and blessings be upon him) and asked him about it. The Prophet (peace and blessings be upon him) replied to them: "You may approach your wife in any manner as long as it is in the (place of) intercourse."
