What was narrated concerning taking off one’s shoes in the graveyard

It was narrated that basher bin Khasasiyyah said:
“While I was walking with the Messenger of Allah ﷺ he said: ‘O son of Khasasiyyah, why are you angry with Allah when you are walking with the Messenger of Allah?’ I said: ‘O Messenger of Allah! I am not angry with Allah at all. Allah has bestowed all good on me.’ Then he passed by the graves of the Muslims and said: ‘They have caught up with a great deal of good.’ Then he passed by the graves of the idolaters and said: ‘They died before a great deal of good came to them.’ Then he turned and saw a man walking between the graves in his shows and he said: ‘O you with the shows, take them off.’”

حَدَّثَنَا عَلِيُّ بْنُ مُحَمَّدٍ، حَدَّثَنَا وَكِيعٌ، حَدَّثَنَا الأَسْوَدُ بْنُ شَيْبَانَ، عَنْ خَالِدِ بْنِ سُمَيْرٍ، عَنْ بَشِيرِ بْنِ نَهِيكٍ، عَنْ بَشِيرِ بْنِ الْخَصَاصِيَةِ، قَالَ بَيْنَمَا أَنَا أَمْشِي، مَعَ رَسُولِ اللَّهِ ﷺ فَقَالَ " يَا ابْنَ الْخَصَاصِيَةِ مَا تَنْقِمُ عَلَى اللَّهِ أَصْبَحْتَ تُمَاشِي رَسُولَ اللَّهِ " . فَقُلْتُ يَا رَسُولَ اللَّهِ مَا أَنْقِمُ عَلَى اللَّهِ شَيْئًا كُلُّ خَيْرٍ قَدْ أَتَانِيهِ اللَّهُ . فَمَرَّ عَلَى مَقَابِرِ الْمُسْلِمِينَ فَقَالَ " أَدْرَكَ هَؤُلاَءِ خَيْرًا كَثِيرًا " . ثُمَّ مَرَّ عَلَى مَقَابِرِ الْمُشْرِكِينَ فَقَالَ " سَبَقَ هَؤُلاَءِ خَيْرٌ كَثِيرٌ " . قَالَ فَالْتَفَتَ فَرَأَى رَجُلاً يَمْشِي بَيْنَ الْمَقَابِرِ فِي نَعْلَيْهِ فَقَالَ " يَا صَاحِبَ السِّبْتِيَّتَيْنِ أَلْقِهِمَا " . حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ مَهْدِيٍّ قَالَ كَانَ عَبْدُ اللَّهِ بْنُ عُثْمَانَ يَقُولُ حَدِيثٌ جَيِّدٌ وَرَجُلٌ ثِقَةٌ .
