Sayyidah Maymunah (may Allah be pleased with her), the freed slave-woman 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)." He (peace and blessings be upon him) said: "It is the land of the Resurrection and the Gathering. Go to it and pray in it, for a single prayer there is equal to a thousand prayers." She said: "What do you say if we do not have the means to travel there or reach it?" He (peace and blessings be upon him) said: "Then send oil there as a gift to be burned in its lamps, for whoever sends oil there as a gift is like one who has prayed there."
