Sahih Muslim 1514
صحيح مسلم#1514SahihUbayy b. Ka'b reported:There was a man, and I do not know of any other man, whose house was farther than his from the mosque and he never missed the prayer (in congregation). It was said to him or I said to him: It you were to buy a donkey you could ride upon it In the dark nights and in the burning sand. He said: I do not like my house to be situated by the side of the mosque, for I (eagerly) desire that my steps towards the mosque and back from it, should be recorded when I return to my family. Upon this the Messenger of Allah (ﷺ) said: Allah has gathered all (rewards) for you
