What is the Prophet Muhammad (saw)'s ruling on praying while sitting?
 Narrated `Imran bin Husain:                     (who had piles) I asked Allah's Apostle about the praying of a man while sitting. He said, "If he prays while standing it is better and he who prays while sitting gets half the reward of that who prays standing; and whoever prays while Lying gets half the reward of that who prays while sitting."
