[Machine] Narrated by the Prophet ﷺ, Gabriel when he struck his heel on the ground, Zamzam water gushed forth. Hagar started gathering pebbles around the water so that it would not disperse. The Messenger of Allah ﷺ said, "May Allah have mercy on Hagar. If she had left it, it would have become a flowing stream."
عَنِ النَّبِيِّ ﷺ أَنَّ جِبْرِيلَ حِينَ رَكَضَ زَمْزَمَ بِعَقِبِهِ فَنَبَعَ الْمَاءُ فَجَعَلَتْ هَاجَرُ تَجْمَعُ الْبَطْحَاءَ حَوْلَ الْمَاءِ لِئَلَّا يَتَفَرَّقَ فَقَالَ رَسُولُ اللهِ ﷺ «رَحِمَ اللهُ هَاجَرَ لَوْ تَرَكَتْهَا لَكَانَتْ عَيْنَا مَعِينًا»
