Sayyidah Maymunah (may Allah be pleased with her) (a different woman from Sayyidah Maymunah, the wife of the Prophet (peace and blessings be upon him)) said: I said: "O Messenger of Allah, give us a ruling about Bayt al-Maqdis (Jerusalem)." The Messenger of Allah (peace and blessings be upon him) said: "It is the land of the Gathering and the Resurrection. Go to it and pray in it, for a prayer there is equal to a thousand prayers." She said: "What do you say about someone who does not have the means to go there?" He (peace and blessings be upon him) said: "If he cannot do that, let him send oil there to be burned in its lamps. Whoever sends (oil) there is like one who has prayed there."
