Sahih Muslim Book - 2, Hadith - 583

و حَدَّثَنَا عُثْمَانُ بْنُ أَبِي شَيْبَةَ حَدَّثَنَا عَلِيُّ بْنُ مُسْهِرٍ عَنْ سَعْدِ بْنِ طَارِقٍ عَنْ رِبْعِىِّ بْنِ حِرَاشٍ عَنْ حُذَيْفَةَ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِنَّ حَوْضِي لَأَبْعَدُ مِنْ أَيْلَةَ مِنْ عَدَنٍ وَالَّذِي نَفْسِي بِيَدِهِ إِنِّي لَأَذُودُ عَنْهُ الرِّجَالَ كَمَا يَذُودُ الرَّجُلُ الْإِبِلَ الْغَرِيبَةَ عَنْ حَوْضِهِ قَالُوا يَا رَسُولَ اللَّهِ وَتَعْرِفُنَا قَالَ نَعَمْ تَرِدُونَ عَلَيَّ غُرًّا مُحَجَّلِينَ مِنْ آثَارِ الْوُضُوءِ لَيْسَتْ لِأَحَدٍ غَيْرِكُمْ.

It was narrated that Hudhaifah said: "The Messenger of Allah (s.a.w) said: 'My Cistern (Hawd) will be larger than the distance between Aylah and 'Adan. By the One in Whose Hand is my soul! I will be driving men away from it as a man drives strange camels away from his cistern.' " They said: "O Messenger of Allah, will you recognize us?" He said: "Yes, you will come to me with glimmering faces and limbs because of the traces of Wudu' and it will not be for anyone other than you."
