Chapter 39
"Your wives are a tilth for you; so go to your tilth (have sexual relations with your wives in any manner as long as it is in the vagina and not in the anus) when or how you will..." (V.2:223)
حَدَّثَنَا أَبُو نُعَيْمٍ، حَدَّثَنَا سُفْيَانُ، عَنِ ابْنِ الْمُنْكَدِرِ، سَمِعْتُ جَابِرًا ـ رضى الله عنه ـ قَالَ كَانَتِ الْيَهُودُ تَقُولُ إِذَا جَامَعَهَا مِنْ وَرَائِهَا جَاءَ الْوَلَدُ أَحْوَلَ. فَنَزَلَتْ {نِسَاؤُكُمْ حَرْثٌ لَكُمْ فَأْتُوا حَرْثَكُمْ أَنَّى شِئْتُمْ}

Jabir:
Jews used to say: "If one has sexual intercourse with his wife from the back, then she will deliver a
squint-eyed child." So this Verse was revealed:--
"Your wives are a tilth unto you; so go to your tilth when or how you will." (2.223)
