The Prophet ﷺ is longing to meet his brothers; Hadith Ikhwani
The Messenger of Allah ﷺ came to the graveyard and said: "Peace be upon you! The abode of the believing people and we, if God so wills, are about to join you. I love to see my brothers." They (the hearers) said: Aren't we your brothers, O Messenger of Allah? He said: You are my companions, and our brothers are those who have, so far, not come into the world. They said: Messenger of Allah, how would you recognise those persons of your Ummah who have not yet been born? He said: Supposing a man had horses with white blazes on foreheads and legs among horses which were all black, tell me, would he not recognise his own horses? They said: Certainly, O Messenger of Allah. He said: They would come with white faces and arms and legs owing to ablution, and I would arrive at the Cistern before them. Some people would be driven away from my Cistern as the stray camel is driven away. I would call out: Come, come. Then it would be said (to me): These people changed themselves after you, and I would say: Be off, be off.
أَنَّ رَسُولَ اللَّهِ ﷺ أَتَى الْمَقْبُرَةَ فَقَالَ «السَّلاَمُ عَلَيْكُمْ دَارَ قَوْمٍ مُؤْمِنِينَ، وَإِنَّا إِنْ شَاءَ اللَّهُ بِكُمْ لاَحِقُونَ۔ 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 رَجُلاً لَهُ خَيْلٌ غُرٌّ مُحَجَّلَةٌ بَيْنَ ظَهْرَىْ خَيْلٍ دُهْمٍ بُهْمٍ أَلاَ يَعْرِفُ خَيْلَهُ؟ قَالُوا: بَلَى يَا رَسُولَ اللَّهِ۔ قَالَ: «فَإِنَّهُمْ يَأْتُونَ غُرًّا مُحَجَّلِينَ مِنَ الْوُضُوءِ، وَأَنَا فَرَطُهُمْ عَلَى الْحَوْضِ۔ أَلاَ لَيُذَادَنَّ رِجَالٌ عَنْ حَوْضِي كَمَا يُذَادُ الْبَعِيرُ الضَّالُّ، أُنَادِيهِمْ، أَلاَ هَلُمَّ، فَيُقَالُ إِنَّهُمْ قَدْ بَدَّلُوا بَعْدَكَ فَأَقُولُ سُحْقًا سُحْقًا۔»
