Imran bin Husain · The Book on Salat (Prayer)

"I asked Allah's Messenger (S) about the Salat for a man who is sitting. He said: 'Whoever performs Salat while standing then that is more virtuous. And whoever performs Salat while sitting, then he gets half the rewards of the one standing, and whoever performs Salat while lying down, then he gets half the rewards of the one sitting.'"

"From Imran bin Husain who said: 'I asked Allah's Messenger (S) about Salat for a sick person. He said: "He performs Salat standing, if he is not able then sitting, if he is not able then on his side."

"The Prophet (S) performed two prostrations after the Salam."
