وَحَدَّثَنَا مُحَمَّدُ بْنُ رُمْحٍ، أَخْبَرَنَا اللَّيْثُ، عَنِ ابْنِ الْهَادِ، عَنْ أَبِي حَازِمٍ، عَنْ مُحَمَّدِ، بْنِ الْمُنْكَدِرِ عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ، أَنَّ يَهُودَ، كَانَتْ تَقُولُ إِذَا أُتِيَتِ الْمَرْأَةُ مِنْ دُبُرِهَا فِي قُبُلِهَا ثُمَّ حَمَلَتْ كَانَ وَلَدُهَا أَحْوَلَ . قَالَ فَأُنْزِلَتْ { نِسَاؤُكُمْ حَرْثٌ لَكُمْ فَأْتُوا حَرْثَكُمْ أَنَّى شِئْتُمْ}
