that the Prophet said: “Allah will not look at a man who has intercourse with his wife in her buttocks.”  

عَنِ النَّبِيِّ ﷺ قَالَ لاَ يَنْظُرُ اللَّهُ إِلَى رَجُلٍ جَامَعَ امْرَأَتَهُ فِي دُبُرِهَا  

That the Messenger of Allah ﷺ said: “Allah is not too shy to tell the truth,” three times. “Do not have intercourse with women in their buttocks.”  

قَالَ رَسُولُ اللَّهِ ﷺ إِنَّ اللَّهَ لاَ يَسْتَحْيِي مِنَ الْحَقِّ ثَلاَثَ مَرَّاتٍ لاَ تَأْتُوا النِّسَاءَ فِي أَدْبَارِهِنَّ  

that he heard Jabir bin 'Abdullah say: “The Jews used to say that if a man has intercourse with a woman in her vagina from the back, the child would have a squint. Then Allah, Glorious is He, revealed: 'Your wives are a tilth for you, so go to your tilth, when or how you will.' ”  

أَنَّهُ سَمِعَ جَابِرَ بْنَ عَبْدِ اللَّهِ يَقُولُ كَانَتْ يَهُودُ تَقُولُ مَنْ أَتَى امْرَأَةً فِي قُبُلِهَا مِنْ دُبُرِهَا كَانَ الْوَلَدُ أَحْوَلَ فَأَنْزَلَ اللَّهُ سُبْحَانَهُ {نِسَاؤُكُمْ حَرْثٌ لَكُمْ فَأْتُوا حَرْثَكُمْ أَنَّى شِئْتُمْ}
