Jabir bin Abdullah reported,

The people grew thirsty on the day of Hudaybiyyah while the Messenger of Allah ﷺ had a small water vessel before him from which he was performing ablution. The people rushed toward him, and he asked, "What is the matter with you?"They replied, "Messenger of Allah, we have no water to drink and none for ablution except what is before you."So the Messenger of Allah ﷺ placed his hand in the vessel, and water began to gush out from between his fingers like springs. We drank and performed ablution from it.I asked, "How many were you?"He answered, "Even had we been a hundred thousand, it would have sufficed us. We were fifteen hundred."

Ahmad 14522

Sahih

حدثنا عبد الصمد بن عبد الوارث حدثنا عبد العزيز بن مسلم حدثنا الحصين عن سالم بن أبي الجعد

عن جابر قال

عطش الناس يوم الحديبية ورسول الله ﷺ بين يديه ركوة يتوضأ منها إذ جهش الناس نحوه فقال ما شأنكم قالوا يا رسول الله إنه ليس لنا ماء نشرب منه ولا ماء نتوضأ به إلا ما بين يديك فوضع رسول الله ﷺ يده في الركوة فجعل الماء يفور من بين أصابعه كأمثال العيون فشربنا وتوضأنا فقلت كم كنتم قال لو كنا مائة ألف كفانا كنا خمس عشرة مائة
