صَحِيحُ مُسْلِمٍ
Sahih Muslim 1435 b
The Book of Marriage
It is permissible for a man to have intercourse with his wife from the front or from the back, without entering the behind
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}
Jabir (b. Abdullah) (Allah be pleased with him) reported that the Jews used to say that when one comes to one's wife through the vagina, but being on her back, and she becomes pregnant, the child has a squint. So the verse came down: " Your wives are your ti'Ith; go then unto your tilth, as you may desire."
