Sahih Bukhari Volume 3, Book 42, Hadith 2369

حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مُحَمَّدٍ، أَخْبَرَنَا عَبْدُ الرَّزَّاقِ، أَخْبَرَنَا مَعْمَرٌ، عَنْ أَيُّوبَ، وَكَثِيرِ بْنِ كَثِيرٍ ـ يَزِيدُ أَحَدُهُمَا عَلَى الآخَرِ ـ عَنْ سَعِيدِ بْنِ جُبَيْرٍ، قَالَ قَالَ ابْنُ عَبَّاسٍ ـ رضى الله عنهما ـ قَالَ النَّبِيُّ صلى الله عليه وسلم ‏"‏ يَرْحَمُ اللَّهُ أُمَّ إِسْمَاعِيلَ، لَوْ تَرَكَتْ زَمْزَمَ ـ أَوْ قَالَ لَوْ لَمْ تَغْرِفْ مِنَ الْمَاءِ ـ لَكَانَتْ عَيْنًا مَعِينًا، وَأَقْبَلَ جُرْهُمُ فَقَالُوا أَتَأْذَنِينَ أَنْ نَنْزِلَ عِنْدَكِ قَالَتْ نَعَمْ وَلاَ حَقَّ لَكُمْ فِي الْمَاءِ‏.‏ قَالُوا نَعَمْ ‏"‏‏.‏

Narrated By Ibn 'Abbas : The Prophet said, "May Allah be merciful to the mother of Ishmael! If she had left the water of Zam-Zam (fountain) as it was, (without constructing a basin for keeping the water), (or said, "If she had not taken handfuls of its water"), it would have been a flowing stream. Jurhum (an Arab tribe) came and asked her, 'May we settle at your dwelling?' She said, 'Yes, but you have no right to possess the water.' They agreed."
