Sayyidah Umm Salamah (may Allah be pleased with her) narrates from the Prophet (peace and blessings be upon him): When the Muhajirun came to Madinah and married among the Ansar, they would come to the women from behind into the front, and the Ansar did not do this. A woman said to her husband that she would ask the Prophet (peace and blessings be upon him). She came, but felt shy; then she asked, and he (peace and blessings be upon him) recited this verse: "Your wives are a tilth for you, so come to your tilth however you wish." [Surah al-Baqarah: 223] "The passage is one."
