" Why does Allah compare the Quran to water?
Besides the fact that the Quran came down from the sky, it also brings dead hearts back to life, like water brings life to the dead earth. Similarly as to how water is completely pure, the Quran is pure and purifies everything else. We are completely incapable of creating water ourselves yet benefit from what it produces in the earth, the same way the Quran is not and cannot be the work of a human being but we can extract benefit from the guidance it offers.
