the Prophet said: "Whoever engages in sexual intercourse with a menstruating woman, or a woman in her anus, consults a soothsayer, then he has disbelieved in what was revealed to Muhammad."  

عَنِ النَّبِيِّ ﷺ قَالَ مَنْ أَتَى حَائِضًا أَوِ امْرَأَةً فِي دُبُرِهَا أَوْ كَاهِنًا فَقَدْ كَفَرَ بِمَا أُنْزِلَ عَلَى مُحَمَّدٍ ﷺ
