Chapter: The signs of Prophethood in Islam
Narrated Anas bin Malik:
I saw Allah's Messenger (ﷺ) at the 'time when the `Asr prayer was due. Then the people were searching for water for ablution but they could not find any. Then some water was brought to Allah's Messenger (ﷺ) and he placed his hand in the pot and ordered the people to perform the ablution with the water. I saw water flowing from underneath his fingers and the people started performing the ablution till all of them did it.
