Sahih Muslim Book - 2, Hadith - 584

حَدَّثَنَا يَحْيَى بْنُ أَيُّوبَ وَسُرَيْجُ بْنُ يُونُسَ وَقُتَيْبَةُ بْنُ سَعِيدٍ وَعَلِيُّ بْنُ حُجْرٍ جَمِيعًا عَنْ إِسْمَاعِيلَ بْنِ جَعْفَرٍ قَالَ ابْنُ أَيُّوبَ حَدَّثَنَا إِسْمَاعِيلُ أَخْبَرَنِي الْعَلَاءُ عَنْ أَبِيهِ عَنْ أَبِي هُرَيْرَةَ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَتَى الْمَقْبُرَةَ 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 مِنْ الْوُضُوءِ وَأَنَا فَرَطُهُمْ عَلَى الْحَوْضِ أَلَا لَيُذَادَنَّ رِجَالٌ عَنْ حَوْضِي كَمَا يُذَادُ الْبَعِيرُ الضَّالُّ أُنَادِيهِمْ أَلَا هَلُمَّ فَيُقَالُ إِنَّهُمْ قَدْ بَدَّلُوا بَعْدَكَ فَأَقُولُ سُحْقًا سُحْقًا.

It was narrated from Abu Hurairah that the Messenger of Allah (s.a.w) came to the graveyard and said: "Peace be upon the abode of believing people, and if Allah wills we will join you soon. Would that we could see our brothers." They said: "Are we not your brothers, O Messenger of Allah?" He said: "You are my Companions. Our brothers are those who have not come yet." They said: "How will you recognize those of your Ummah who have not come yet, O Messenger of Allah?" He said: "Do you not see that if a man has a horse that has a white blaze and white feet among horses that are all black, will he not recognize his horse?" They said: "Of course, O Messenger of Allah!" He said: "You will come to me with glimmering faces and limbs (like the white markings of a horse) because of the traces of Wudu'. I will reach the Cistern (Hawd) before them. And Lo! Men will be driven away from my Cistern as stray camels are driven away. I will call out to them: 'Come here!' but it will be said: 'They changed after you were gone.' And I will say: 'Away with you, away with you!"'
