It is narrated from Hazrat Imran bin Husain (may Allah be pleased with him) that I was suffering from many illnesses at the same time. I asked the Prophet (peace and blessings be upon him) about performing prayer while sitting. The Prophet (peace and blessings be upon him) said: The reward for performing prayer while sitting is half of that for performing prayer while standing, and the reward for performing prayer while lying down is half of that for performing prayer while sitting.
