Abu Hurairah used to carry a water vessel for the Prophet ﷺ for his ablution and personal needs. Once, while he was following him with it, the Prophet ﷺ asked, "Who is this?"He replied, "I am Abu Hurairah."The Prophet ﷺ said, "Bring me some stones I can use to clean myself, but do not bring me a bone or dung."So I brought him some stones, carrying them in the edge of my garment, and placed them beside him, then I left. When he had finished, I walked with him and asked, "What is wrong with bones and dung?"He replied, "They are food for the jinn. A delegation of the jinn of Nasibin came to me, and what excellent jinn they are. They asked me for provisions, so I prayed to Allah that they would not pass by a bone or piece of dung without finding food on it."
أنه كان يحمل مع النبي ﷺ إداوة لوضوئه وحاجته، فبينما هو يتبعه بها، فقال: من هذا؟ فقال: أنا أبو هريرة، فقال: ابغني أحجارا أستنفض بها، ولا تأتني بعظم ولا بروثة، فأتيته بأحجار أحملها في طرف ثوبي، حتى وضعت إلى جنبه ثم انصرفت، حتى إذا فرغ مشيت، فقلت: ما بال العظم والروثة؟ قال: هما من طعام الجن، وإنه أتاني وفد جن نصيبين، ونعم الجن، فسألوني الزاد، فدعوت الله لهم أن لا يمروا بعظم ولا بروثة إلا وجدوا عليها طعاما.
