…The Glorious Lord mentioned to the venerable Moses some of the bounties He had granted the Community of Muhammad: “Moses, I have given the Community of Muhammad two lights, so that two darknesses may not harm them.” The venerable Converser of Allāh the asked: “What are these lights You have given to the Community of Muhammad, O my Lord?” Allāh, glorified is He, replied: “One is the light of Ramadān, the other the light of the Qur’ān.” “My Lord,” asked the venerable Moses: “What are the two darknesses?” and the Glorified One answered: “One is the darkness of the tomb, while the second is the darkness of the Day of Resurrection.” The tomb of one who recites the Qur’ān is illumined with the light of the Qur’ān, so that he does not see the darkness of the grave. The light of Ramadān will not leave a person in darkness at the Place of Resurrection.
