Are there any Hadiths which say that the Zam Zam well will never dry out of water?
The following suitable Hadiths indicate that the water of Zam Zam will remain and not dry out:
1) In the narration regarding Sayyidah Hajar (radiyallahu ‘anha) collecting the Zam zam water, Jibril (‘alayhis salam) said to her, ‘Do not fear thirst for the people of this valley, for it is a spring from which the guests of Allah will [continue] to drink.”
(Akhbaru Makkah of Imam Fakihi, Hadith: 1051. Refer: Fathul Bari, Hadith: 3364)
2) In a lengthy narration of Sahih Bukhari which discusses the incident of Ibrahim (‘alayhis salam) and Hajar (radiyallahu ‘anha), Jibril (‘alayhis salam) said to Hajar (radiyallahu ‘anha) after she drank Zam zam and breastfed Isma’il (‘alayhis salam): “…Do not fear destruction…” (Sahih Bukhari, Hadith: 3364).
Hafiz Ibn Hajar (rahimahullah) and ‘Allamah ‘Ayni (rahimahullah) have cited another version of this narration which states that Jibril (‘alayhis salam) told her, ‘Do not fear that the water will be depleted/run out…’
(Fathul Bari, and ‘Umdatul Qari, Hadith: 3364)
