Sunan Ibn Majah
Sunan Ibn Majah 1925
حَدَّثَنَا سَهْلُ بْنُ أَبِي سَهْلٍ، وَجَمِيلُ بْنُ الْحَسَنِ، قَالاَ حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ، عَنْ مُحَمَّدِ بْنِ الْمُنْكَدِرِ، 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} .

Jabir ibn Abdullah said: The Jews used to say, ‘If a man approaches a woman from behind, entering her vagina, the child will be cross-eyed.’ Then Allah, Glorified is He, revealed: ‘Your wives are a tilth for you, so come to your tilth however you wish.’
Notes and open questions — unreviewed
The source specifies approaching from behind while entering the vagina; it does not describe anal intercourse.
