The Prophet ﷺ said, "Allah will not look at a man who has intercourse with his wife in her anus."
عن النبي ﷺ: لا ينظر الله إلى رجل جامع امرأته في دبرها.
It was narrated by Abu Dawud (2162), Ibn Majah (1923), Ahmad (7684), Abdul-Razzaq (20952), and Bayhaqi (7/198), all of them through the hadith of Suhayl bin Abu Salih, from Harith bin Mukhlid, from Abu Hurairah, who related it.The wording in Abu Dawud is, "Cursed is the one who has intercourse with his wife in her rear." Its chain is hasan because of Harith bin Mukhlid, who is Zurqi Ansari. Two narrators related from him, and Ibn Hibban mentioned him among the trustworthy narrators. He is one of the Tabiin, and someone like him has his hadith graded hasan when his hadith has sound foundations and contains no irregularity or objectionable content. This is the case here.Ibn Abdul-Hadi also deemed its chain sound in Tanqih Tahqiq (2769).
