Hadith 2039
Sayyiduna Anas bin Malik (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) was on a journey with his companions, and fasting became very difficult for his companions. So the Messenger of Allah (peace and blessings be upon him) asked for a vessel in which there was water, and he (peace and blessings be upon him) drank it while sitting on his mount, while the companions were looking towards him.
