"I asked Masruq, 'Who informed the Prophet ﷺ about the Jinns at the night when they heard the Qur'an?' He said, 'Your father ʿAbdullah informed me that a tree informed the Prophet ﷺ about them.' "  

سَأَلْتُ مَسْرُوقًا مَنْ آذَنَ النَّبِيَّ ﷺ بِالْجِنِّ لَيْلَةَ اسْتَمَعُوا الْقُرْآنَ فَقَالَ حَدَّثَنِي أَبُوكَ يَعْنِي عَبْدَ اللَّهِ أَنَّهُ آذَنَتْ بِهِمْ شَجَرَةٌ  

That once he was in the company of the Prophet ﷺ carrying a water pot for his ablution and for cleaning his private parts. While he was following him carrying it (i.e. the pot), the Prophet ﷺ said, "Who is this?" He said, "I am Abu Huraira." The Prophet ﷺ said, "Bring me stones in order to clean my private parts, and do not bring any bones or animal dung." Abu Huraira went on narrating: So I brought some stones, carrying them in the corner of my robe till I put them by his side and went away. When he finished, I walked with him and asked, "What about the bone and the animal dung?" He said, "They are of the food of Jinns. The delegate of Jinns of (the city of) Nasibin came to me--and how nice those Jinns were--and asked me for the remains of the human food. I invoked Allah for them that they would never pass by a bone or animal dung but find food on them."  

أَنَّهُ كَانَ يَحْمِلُ مَعَ النَّبِيِّ ﷺ إِدَاوَةً لِوَضُوئِهِ وَحَاجَتِهِ فَبَيْنَمَا هُوَ يَتْبَعُهُ بِهَا فَقَالَ مَنْ هَذَا فَقَالَ أَنَا أَبُو هُرَيْرَةَ فَقَالَ ابْغِنِي أَحْجَارًا أَسْتَنْفِضْ بِهَا وَلاَ تَأْتِنِي بِعَظْمٍ وَلاَ بِرَوْثَةٍ فَأَتَيْتُهُ بِأَحْجَارٍ أَحْمِلُهَا فِي طَرَفِ ثَوْبِي حَتَّى وَضَعْتُ إِلَى جَنْبِهِ ثُمَّ انْصَرَفْتُ حَتَّى إِذَا فَرَغَ مَشَيْتُ فَقُلْتُ مَا بَالُ الْعَظْمِ وَالرَّوْثَةِ قَالَ هُمَا مِنْ طَعَامِ الْجِنِّ وَإِنَّهُ أَتَانِي وَفْدُ جِنِّ نَصِيبِينَ وَنِعْمَ الْجِنُّ فَسَأَلُونِي الزَّادَ فَدَعَوْتُ اللَّهَ لَهُمْ أَنْ لاَ يَمُرُّوا بِعَظْمٍ وَلاَ بِرَوْثَةٍ إِلاَّ وَجَدُوا عَلَيْهَا طَعَامًا
