Hadith 10:110
Khuzaima b. Thabit reported the Prophet as saying, “God is not ashamed of the truth. Do not have intercourse with women through the anus.” Ahmad, Tirmidhi, Ibn Majah and Darimi transmitted it.
وَعَنْ خُزَيْمَةَ بْنِ ثَابِتٍ: أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «إِنَّ اللَّهَ لَا يستحيي مِنَ الْحَقِّ لَا تَأْتُوا النِّسَاءَ فِي أَدْبَارِهِنَّ» . رَوَاهُ أَحْمد وَالتِّرْمِذِيّ وَابْن مَاجَه. والدارمي
