حَدَّثَنِي أَحْمَدُ بْنُ عَبْدِ اللَّهِ بْنِ يُونُسَ، حَدَّثَنَا زَائِدَةُ، حَدَّثَنَا عَبْدُ الْمَلِكِ بْنُ عُمَيْرٍ، قَالَ سَمِعْتُ جُنْدَبًا، يَقُولُ سَمِعْتُ النَّبِيَّ صلى الله عليه وسلم يَقُولُ ‏"‏ أَنَا فَرَطُكُمْ، عَلَى الْحَوْضِ ‏"‏ ‏.‏

'Abdullah reported Allah's Messenger (ﷺ) as saying

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.
