Mukhtasar Muslim

Sayyiduna Anas (may Allah be pleased with him) says: We were with the Messenger of Allah (peace and blessings of Allah be upon him) on a journey. Some of us were fasting and some were not. We halted at a place during intense heat. Among us, the one who had a sheet had the most shade, and there were some who were shielding themselves from the sun with their hands. All those who were fasting lay down at the place, and those who were not fasting stood up and set up tents and gave water to the camels. So the Messenger of Allah (peace and blessings of Allah be upon him) said: "Those who broke their fast today have taken much reward."
