Ibn Sabit said: I asked Hafsah bint Abdur Rahman, Abdur Rahman who was the son of Abu Bakr. I asked Hafsah: I want to ask you about something, but I feel shy. She said: (Son) Nephew, ask what you want to ask. I said: I want to ask about intercourse with women in the anus. She replied that Lady Umm Salamah (may Allah be pleased with her) narrated to me, saying that the Ansar did not have intercourse with their wives lying on their faces or stomachs (i.e., upside down), but the Muhajirun used to do so. One of the Muhajirun married an Ansari woman and wanted to have intercourse with her in that manner, but she refused. That woman came to Lady Umm Salamah (may Allah be pleased with her) and told her the story. When the Messenger of Allah (peace and blessings be upon him) arrived, the woman went out due to shyness, so Lady Umm Salamah (may Allah be pleased with her) narrated the incident to the Prophet (peace and blessings be upon him). He said: "Call her to me." She was called, and the Prophet (peace and blessings be upon him) recited this noble verse: «﴿نِسَاؤُكُمْ حَرْثٌ لَكُمْ فَأْتُوا حَرْثَكُمْ أَنَّى شِئْتُمْ﴾» [بقره: 223/2] meaning, "Your wives are your tilth, so come to your tilth as you wish." He said: "In one opening or way only."
