Hadith 8:56
Narrated Abu Hurairah (RA):
Allah's Messenger (ﷺ) said: "He who has intercourse with a woman through her anus is accursed." [Abu Dawud and an-Nasa'i reported it and the wording is his (an-Nasa'i). Its narrators are reliable, but it was considered to be defective for being Mursal (a missing link after the Tabi'i)].
عَنْ أَبِي هُرَيْرَةَ - رضى الله عنه - قَالَ : قَالَ رَسُولُ اَللَّهِ - صلى الله عليه وسلم -{ مَلْعُونٌ مَنْ أَتَى اِمْرَأَةً فِي دُبُرِهَا } رَوَاهُ أَبُو دَاوُدَ , وَالنَّسَائِيُّ وَاللَّفْظُ لَهُ , وَرِجَالُهُ ثِقَاتٌ , وَلَكِنْ أُعِلَّ بِالْإِرْسَالِ
