Sayyiduna Bilal bin Rabah (may Allah be pleased with him) says: I came to the Messenger of Allah (peace and blessings be upon him) to inform him about the prayer, while he intended to fast. So the Messenger of Allah (peace and blessings be upon him) had a bowl brought, drank from it himself, and gave me to drink as well. After that, the Messenger of Allah (peace and blessings be upon him) proceeded towards the mosque for prayer and began to pray without performing ablution, while he intended to fast.
