Sunan an-Nasa'i 2048
It was narrated that Bashir bin Al-Khasasiyyah said:
"I was waliking with the Messenger of Allah and he passed by the graves of the Muslims and aid: 'They died before a great deal of evil came to them.' Then he passed by the grave of  the idolators and said: 'They died before a great deal of good came to them.' Then he rurned, and he saw a man walking between the graves in his sandals and he said; 'O you with the Sibtiyah sandals, take them off"'. (Shahih)
أَخْبَرَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ الْمُبَارَكِ، قَالَ حَدَّثَنَا وَكِيعٌ، عَنِ الأَسْوَدِ بْنِ شَيْبَانَ، - وَكَانَ ثِقَةً - عَنْ خَالِدِ بْنِ سُمَيْرٍ، عَنْ بَشِيرِ بْنِ نَهِيكٍ، أَنَّ بَشِيرَ ابْنَ الْخَصَاصِيَّةِ، قَالَ كُنْتُ أَمْشِي مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم فَمَرَّ عَلَى قُبُورِ الْمُسْلِمِينَ فَقَالَ ‏"‏ لَقَدْ سَبَقَ هَؤُلاَءِ شَرًّا كَثِيرًا ‏"‏ ‏.‏ ثُمَّ مَرَّ عَلَى قُبُورِ الْمُشْرِكِينَ فَقَالَ ‏"‏ لَقَدْ سَبَقَ هَؤُلاَءِ خَيْرًا كَثِيرًا ‏"‏ ‏.‏ فَحَانَتْ مِنْهُ الْتِفَاتَةٌ فَرَأَى رَجُلاً يَمْشِي بَيْنَ الْقُبُورِ فِي نَعْلَيْهِ فَقَالَ ‏"‏ يَا صَاحِبَ السِّبْتِيَّتَيْنِ أَلْقِهِمَا ‏"‏ ‏.‏
