Sahih Muslim · Book 43: The Book of Virtues · The Cistern Of Our Prophet (SAW) And Its Attributes
'Abdullah reported Allah's Messenger (ﷺ) as saying:
وَحَدَّثَنِي حَرْمَلَةُ بْنُ يَحْيَى ، حَدَّثَنَا عَبْدُ اللَّهِ بْنُ وَهْبٍ ، حَدَّثَنِي عُمَرُ بْنُ مُحَمَّدٍ ، عَنْ نَافِعٍ ، عَنْ عَبْدِ اللَّهِ ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " إِنَّ أَمَامَكُمْ حَوْضًا كَمَا بَيْنَ جَرْبَا وَأَذْرُحَ فِيهِ أَبَارِيقُ كَنُجُومِ السَّمَاءِ مَنْ وَرَدَهُ فَشَرِبَ مِنْهُ لَمْ يَظْمَأْ بَعْدَهَا أَبَدًا " .
There would be before you a Cistern (as extensive) as there is the distance between Jarba' and Adhruh and there would be jugs like stars in the sky; he who would come to that and drink from it would never feel thirsty after that.
