Sahih Muslim 2299eBook 43, Hadith 49
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 " .
