وَعَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ
قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «مَنْ أَتَى حَائِضًا أَوِ امْرَأَةً فِي دُبُرِهَا أَوْ كَاهِنًا فَقَدْ كَفَرَ بِمَا أُنْزِلَ عَلَى مُحَمَّدٍ»
“If anyone has intercourse with a woman who is menstruating, or uses preposterous venery with a woman1, or visits a kahin, he has disbelieved in what has been sent down to Muhammad.” Tirmidhi, Ibn Majah and Darimi transmitted it. In the version of the last two he declared him to be right in saying that he has disbelieved. Tirmidhi said, “We know this tradition only from Hakim al-Athram from Abu Tamima from Abu Hurayrah” 1: i.e. enters her from her behind.
