Hudhaifa reported:
وَحَدَّثَنَا عُثْمَانُ بْنُ أَبِي شَيْبَةَ ، حَدَّثَنَا عَلِيُّ بْنُ مُسْهِرٍ ، عَنْ سَعْدِ بْنِ طَارِقٍ ، عَنْ رِبْعِيِّ بْنِ حِرَاشٍ ، عَنْ حُذَيْفَةَ ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " إِنَّ حَوْضِي لأَبْعَدُ مِنْ أَيْلَةَ مِنْ عَدَنٍ وَالَّذِي نَفْسِي بِيَدِهِ إِنِّي لأَذُودُ عَنْهُ الرِّجَالَ كَمَا يَذُودُ الرَّجُلُ الإِبِلَ الْغَرِيبَةَ عَنْ حَوْضِهِ " . قَالُوا يَا رَسُولَ اللَّهِ وَتَعْرِفُنَا قَالَ " نَعَمْ تَرِدُونَ عَلَىَّ غُرًّا مُحَجَّلِينَ مِنْ آثَارِ الْوُضُوءِ لَيْسَتْ لأَحَدٍ غَيْرِكُمْ " .
The Messenger of Allah (ﷺ) said: My Cistern is bigger than the space between Aila and Aden. By Him in Whose Hand is my life, I will drive away persons (from it) just as a person drives away unknown camels from his cistern. They (the companions) said: Messenger of Allah, would you recognise us? He said: Yes, you would come to me with white faces, and white hands and feet on account of the traces of ablution. None but you would have (this mark).
