"None of you should urinate into a burrow in the ground." They said to Qatadah: "Why is it disliked to urinate into a burrow in the ground?" He said: "It is said that these are dwelling-places of the jinn." (Using translation from Nasāʾī 34)  

«لَا يَبُولَنَّ أَحَدُكُمْ فِي جُحْرٍ» قِيلَ لِقَتَادَةَ وَمَا يُكْرَهُ مِنَ الْبَوْلِ فِي الْجُحْرِ؟ قَالَ يُقَالُ إِنَّهَا مَسَاكِنُ الْجِنِّ
