A Bedouin came to the Prophet ﷺ and said: O Messenger of Allah, what if we are in the desert and a little wind comes out of one of us? The Messenger of Allah ﷺ said: “Allah, may He be glorified and exalted, not too shy to tell the truth. If one of you does that, let him do wudooʿ. And do not approach women in their back passage [and once he said: in their anuses].ʿ
جَاءَ أَعْرَابِيٌّ إِلَى النَّبِيِّ ﷺ فَقَالَ يَا رَسُولَ اللهِ إِنَّا نَكُونُ بِالْبَادِيَةِ فَتَخْرُجُ مِنْ أَحَدِنَا الرُّوَيْحَةُ؟ فَقَالَ رَسُولُ اللهِ ﷺ إِنَّ اللهَ ﷻ لَا يَسْتَحْيِي مِنَ الْحَقِّ إِذَا فَعَلَ أَحَدُكُمْ فَلْيَتَوَضَّأْ وَلا تَأْتُوا النِّسَاءَ فِي أَعْجَازِهِنَّ وَقَالَ مَرَّةً فِي أَدْبَارِهِنَّ
