Muhammad bin Al Munkadir said I heard Jabir say The Jews used to say “When a man has intercourse with his wife through the vagina, but being on her back the child will have a squint, so the verse came down. Your wives are a tilth to you, so come to your tilth however you will.”

سَمِعْتُ جَابِرًا يَقُولُ إِنَّ الْيَهُودَ يَقُولُونَ إِذَا جَامَعَ الرَّجُلُ أَهْلَهُ فِي فَرْجِهَا مِنْ وَرَائِهَا كَانَ وَلَدُهُ أَحْوَلَ فَأَنْزَلَ اللَّهُ سُبْحَانَهُ وَتَعَالَى { نِسَاؤُكُمْ حَرْثٌ لَكُمْ فَأْتُوا حَرْثَكُمْ أَنَّى شِئْتُمْ }
