Sayyiduna Anas (may Allah be pleased with him) narrates that we were with the Messenger of Allah (peace and blessings be upon him) on a journey. Some of us were fasting and some had not kept the fast. We halted at a station on a very hot day in intense heat. Some among us were shielding themselves from the sun with their hands, and the person who had a sheet had the most shade among us, and the fasting people were taking place in his shade. Those who had not kept the fast got up and pitched the tents and gave water to the riding animals. So the Messenger of Allah (peace and blessings be upon him) said: "Today, those who did not fast have taken the reward."
