It is narrated from Hazrat Bilal Habashi (may Allah be pleased with him) that once I went to the court of the Messenger (peace and blessings be upon him) to inform him about the prayer (the Prophet, peace and blessings be upon him, intended to fast). The Prophet (peace and blessings be upon him) asked for a bowl, drank its water himself, and also gave me to drink. Then he proceeded to the mosque for prayer and led the prayer without performing a fresh ablution.
