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.
أَنَّ رَسُولَ اللَّهِ ﷺ 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. (Using translation from Muslim 2299e)
قَالَ رَسُولُ اللهِ ﷺ إِنَّ أَمَامَكُمْ حَوْضًا كَمَا بَيْنَ جَرْبَاءَ وَأَذْرُحَ فِيهِ أَبَارِيقُ كَنُجُومِ السَّمَاءِ مَنْ وَرَدَهُ فَشَرِبَ مِنْهُ لَمْ يَظْمَأْ بَعْدَهَا أَبَدًا
"إِنَّ أَمامكم حوضًا كمَا بين جربَاءَ، وأَذرُحَ -فيه- أَباريق كنُجُم السَّمَاءِ، من وَرَدَهُ فَشَرِبَ مِنهُ لم يظمأ بعدهَا أَبدًا".
