Sunan Ibn Majah, Chapter: The Chapters of Establishing the Prayer and the Sunnah Regarding Them

the freed (female) slave of the Prophet (saw): I said: "O Messenger of Allah (saw_, tell us about Baitil-Maqdis." He said: "It is the land of the Resurrection and the Gathering. Go and pray there, for one prayer there is like one thousand prayers elsewhere." I said: "What if I cannot travel and go there?" He said: "Then send a gift of oil to light its lamps, for whoever does that is like one who goes there."
