question #1 Sahih al-Bukhari 1115, Book 18, Hadith 35 : What is the significance of praying while standing compared to sitting or lying down in terms of reward?

(who had piles) I asked Allah’s Messenger (ﷺ) 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.”
