Sayyiduna Ibn Abbas (may Allah be pleased with them both) said: The Messenger of Allah (peace and blessings be upon him) travelled in Ramadan. His Companions complained to him of thirst, so he (peace and blessings be upon him) called for water and drank. At that, some of the people broke their fast and some kept fasting, and neither group found fault with what the other did.
