Anas bin Malik reported,

I saw the Messenger of Allah ﷺ when the time for the afternoon prayer arrived. The people searched for water to perform ablution but could not find any. Then water for ablution was brought to the Messenger of Allah ﷺ, and he placed his hand in that vessel and instructed the people to perform ablution from it. I watched the water gushing forth from beneath his fingers until every last one of them had performed ablution.

عن أنس بن مالك أنه قال

رأيت رسول الله ﷺ وحانت صلاة العصر فالتمس الناس الوضوء فلم يجدوه فأتي رسول الله ﷺ بوضوء فوضع رسول الله ﷺ في ذلك الإناء يده وأمر الناس أن يتوضئوا منه قال فرأيت الماء ينبع من تحت أصابعه حتى توضئوا من عند آخرهم
