Sahih al-Bukhari 2368
Narrated Ibn `Abbas:
The Prophet (ﷺ) said, "May Allah be merciful to the mother of Ishmael! If she had left the water of 
Zamzam (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."
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 ‏"‏‏.‏
