وَعَنْ أَبِي هُرَيْرَةَ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسلم أَتَى الْمَقْبَرَةَ فَقَالَ: «السَّلَامُ عَلَيْكُمْ دَارَ قَوْمٍ مُؤْمِنِينَ وَإِنَّا إِنْ شَاءَ اللَّهُ بِكُمْ لَاحِقُونَ وَدِدْتُ أَنَّا قَدْ رَأَيْنَا إِخْوَانَنَا قَالُوا أَوَلَسْنَا إِخْوَانَكَ يَا رَسُولَ اللَّهِ قَالَ أَنْتُمْ أَصْحَابِي وَإِخْوَانُنَا الَّذِينَ لَمْ يَأْتُوا بَعْدُ فَقَالُوا كَيْفَ تَعْرِفُ مَنْ لَمْ يَأْتِ بَعْدُ مِنْ أُمَّتِكَ يَا رَسُولَ اللَّهِ فَقَالَ أَرَأَيْتَ لَوْ أَنَّ رَجُلًا لَهُ خَيْلٌ غُرٌّ مُحَجَّلَةٌ بَيْنَ ظَهْرَيْ خَيْلٍ دُهْمٍ بُهْمٍ أَلَا يَعْرِفُ خَيْلَهُ قَالُوا بَلَى يَا رَسُولَ اللَّهِ قَالَ فَإِنَّهُمْ يَأْتُونَ غُرًّا مُحَجَّلِينَ مِنَ الْوُضُوءِ وَأَنَا فَرَطُهُمْ عَلَى الْحَوْض» . رَوَاهُ مُسلم

Abu Huraira told of God’s messenger coming to the cemetery and saying, “Peace be upon you, believing ones, and if God will we shall join you. I wish we had seen our brethren.” He was asked, “Are we not your brethren, messenger of God?” and replied, “You are my companions; our brethren are those who have not yet been born.” They asked, “How will you recognise those members of your people who have not yet been born, messenger of God?” He said, “Tell me; supposing a man had horses with white blazes and white marks on their legs among horses which were pure black, would he not recognise his own horses?” They replied, “Certainly, messenger of God.” He said, “They will come with white faces and arms and legs owing to ablution, and I will arrive at the Tank before them.” Muslim transmitted it.
