[Machine] The Messenger of Allah ﷺ performed his prayer while wearing his sandals, then he took them off. It was said to him, so he said, "Indeed, Jibreel came to me and informed me that there was impurity in them. So when you come to the mosque, look at your sandals. Whoever finds anything should wipe it off." Reported by Ishaq al-Hanzali from Abdur-Razzaq from Ma'mar from Ayyub from a man who narrated from Abu Sa'eed al-Khudri, and he said, "Impurity" and did not say "filthiness".  

صَلَّى رَسُولُ اللهِ ﷺ فِي نَعْلَيْهِ ثُمَّ خَلَعَهُمَا فَقِيلَ لَهُ فَقَالَ إِنَّ جَبْرَائِيلَ جَاءَنِي فَأَخْبَرَنِي أَنَّ فِيهِمَا خَبَثًا فَإِذَا جِئْتُمُ الْمَسْجِدَ فَانْظُرُوا فِي نِعَالِكُمْ فَمَنْ وَجَدَ شَيْئًا فَلْيَحُكَّهُ وَرَوَاهُ إِسْحَاقُ الْحَنْظَلِيُّ عَنْ عَبْدِ الرَّزَّاقِ عَنْ مَعْمَرٍ عَنْ أَيُّوبَ عَنْ رَجُلٍ حَدَّثَهُ عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ وَقَالَ قَذَرًا وَلَمْ يَقُلْ خَبَثًا
