The Messenger of Allah (s) said: If a believer dies, leaving behind one sheet of knowledge, that sheet will be a curtain between him and the Fire on the Day of Resurrection. For every letter written on it, Allah will grant him a city that is seven times wider than this world. A believer does not sit to learn for one moment except that his Lord calls to him, saying: “You have sat to attend to My beloved. By My glory and My majesty! I will have you live in Paradise with it, regardless [of your sins].”
