"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)
كُنْتُ أَمْشِي مَعَ رَسُولِ اللَّهِ ﷺ 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
