[Machine] I was behind Abu Huraira as he was performing ablution for prayer, and he would extend his hands until he reached his armpits. I heard my beloved (Prophet Muhammad) say, "The beautiful garment of a believer extends to where the ablution reaches."  

كُنْتُ خَلْفَ أَبِي هُرَيْرَةَ وَهُوَ يَتَوَضَّأُ لِلصَّلَاةِ فَكَانَ يَمُدُّ يَدَيْهِ حَتَّى يَبْلُغَ إِبْطَيْهِ قَالَ سَمِعْتُ خَلِيلِي يَقُولُ «تَبْلُغُ الْحِلْيَةُ مِنَ الْمُؤْمِنِ حَيْثُ يَبْلُغُ الْوُضُوءُ»  

"Peace be upon you, abode of believing people. If Allah wills, we shall join you soon. Would that I had seen our brothers." They said: "O Messenger of Allah, are we not your brother?" He said: "You are my Companions. My brothers are those who have not come yet. And I will reach the Hawd before you." They said: "O Messenger of Allah, how will you know those of your Ummah who come after you?" He said: "Don't you think that if a man has a horse with a white blaze and white feet among horses that are solid black, he will recognize his horse?" They said: "Of course." He said: "They will come on the Day of Resurrection with glittering white faces and glittering white hands and feet because of Wudu', and I will reach the Hawd before them." (Using translation from Nasāʾī 150)  

أَنَّ رَسُولَ اللهِ ﷺ خَرَجَ إِلَى الْمَقْبُرَةِ فَقَالَ «السَّلَامُ عَلَيْكُمْ دَارَ قَوْمٍ مُؤْمِنِينَ وَإِنَّا إِنْ شَاءَ اللهُ بِكُمْ لَاحِقُونَ وَدِدْتُ أَنِّي قَدْ رَأَيْتُ إِخْوَانَنَا» قَالُوا يَا رَسُولَ اللهِ أَلَسْنَا بِإِخْوَانِكَ؟ قَالَ «بَلْ أَنْتُمْ أَصْحَابِي وَإِخْوَانُنَا الَّذِي لَمْ يَأْتُوا بَعْدُ وَأَنَا فَرَطُهُمْ عَلَى الْحَوْضِ» قَالُوا يَا رَسُولَ اللهِ كَيْفَ تَعْرِفُ مَنْ يَأْتِي بَعْدَكَ مِنْ أُمَّتِكَ؟ قَالَ «أَرَأَيْتَ لَوْ كَانَ لِرَجُلٍ خَيْلٌ غُرٌّ مُحَجَّلَةٌ فِي خَيْلٍ دُهْمٍ بُهْمٍ أَلَا يُعْرَفُ خَيْلَهُ؟» قَالُوا بَلَى قَالَ «فَإِنَّهُمْ يَأْتُونَ يَوْمَ الْقِيَامَةِ غُرًّا مُحَجَّلِينَ مِنْ الْوُضُوءِ وَأنا فَرَطُهُمْ عَلَى الْحَوْضِ»
