It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that when the Prophet (peace and blessings be upon him) came to Madinah, an epidemic fever was spreading there, as a result of which the people fell ill with fever. Then the Prophet (peace and blessings be upon him) came into the mosque and saw that the people were praying sitting. He (peace and blessings be upon him) said: "The reward of the one who prays sitting is half that of the one who prays standing." (Sayyiduna Anas (may Allah be pleased with him) said:) On hearing this, the people, for the sake of the reward, bore the hardship and began to pray standing.
