Sahih Muslim , Hadith 248 ⓘ

Hudhaifa reported: The Messenger of Allah 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).

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 ‏"‏ ‏.‏
