Hadith #3

عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ سَهْلِ بْنِ زِيَادٍ عَنْ جَعْفَرِ بْنِ مُحَمَّدٍ الْأَشْعَرِيِّ عَنِ ابْنِ الْقَدَّاحِ عَنْ أَبِي عَبْدِ اللَّهِ ( عليه السلام ) قَالَ قَالَ أَمِيرُ الْمُؤْمِنِينَ ( عليه السلام ) مَاءُ زَمْزَمَ خَيْرُ مَاءٍ عَلَى وَجْهِ الْأَرْضِ وَ شَرُّ مَاءٍ عَلَى وَجْهِ الْأَرْضِ مَاءُ بَرَهُوتَ الَّذِي بِحَضْرَمَوْتَ تَرِدُهُ هَامُ الْكُفَّارِ بِاللَّيْلِ .

3. A number of our people have narrated from Sahl ibn Ziyad from Ja‘far ibn Muhammad al-Ash‘ariy from ibn al-Qaddah who has said the following: “Abu ’Abd Allah, ‘Alayhi al-Salam, has said that ’Amir al-Mu’minin has said, ‘The water of Zamzam is the best water on earth. The worst water on earth is the water of Barhut which is in Hadra maxvt upon which wandering unbelievers roam during the night.’”
