It was narrated from Qatadah, from 'Abdullah bin Sarjis, that the Prophet of Allah ﷺ said:

"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."

أَخْبَرَنَا عُبَيْدُ اللَّهِ بْنُ سَعِيدٍ، قَالَ أَنْبَأَنَا مُعَاذُ بْنُ هِشَامٍ، قَالَ حَدَّثَنِي أَبِي، عَنْ قَتَادَةَ، عَنْ عَبْدِ اللَّهِ بْنِ سَرْجِسَ، أَنَّ نَبِيَّ اللَّهِ ﷺ قَالَ " لاَ يَبُولَنَّ أَحَدُكُمْ فِي جُحْرٍ " . قَالُوا لِقَتَادَةَ وَمَا يُكْرَهُ مِنَ الْبَوْلِ فِي الْجُحْرِ قَالَ يُقَالُ إِنَّهَا مَسَاكِنُ الْجِنِّ .
