Hadith on Kahin: Whoever believes a soothsayer, disbelieves in the Prophet

Abu Huraira reported: The Messenger of Allah, peace and blessings be upon him, said, “Whoever goes to a fortuneteller and believes in what he says, or approaches his wife for intercourse while she is menstruating, or approaches his wife for intercourse from her backside, he was nothing to do with what has been revealed to Muhammad.

عَنْ أَبِي هُرَيْرَةَ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مَنْ أَتَى كَاهِنًا فَصَدَّقَهُ بِمَا يَقُولُ أَوْ أَتَى امْرَأَتَهُ حَائِضًا أَو أَتَى امْرَأَته من دُبُرِهَا فَقَدْ بَرِئَ مِمَّا أُنْزِلَ عَلَى مُحَمَّدٍ
