It is narrated from Hazrat Imran (may Allah be pleased with him) that he asked the Prophet (peace and blessings be upon him) about performing prayer while sitting. The Prophet (peace and blessings be upon him) said: Performing prayer while standing is the most virtuous; the reward for performing prayer while sitting is half of that of performing prayer while standing, and the reward for performing prayer while lying down is half of that of performing prayer while sitting.
