Abdullah bin Sawadah reports from his father that Sayyiduna Anas bin Malik (may Allah be pleased with him), who was one of them, said that his camels were lost and he came to Madinah in search of them. He came to the Prophet (peace and blessings be upon him) while he (peace and blessings be upon him) was eating. He (peace and blessings be upon him) said: "Come and eat." He said: I am fasting. Then he (peace and blessings be upon him) said: "Indeed, fasting has been remitted for the traveller, the pregnant woman or the nursing woman, and the prayer has been lightened for the traveller."
