"The Dwarves have a peculiar history. The first Seven Fathers of the Dwarves were actually created before the Elves by Aulë, beneath the mountains and against the will of Eru Ilúvatar. Eru was displeased with Aulë's rogue action, and ordered them destroyed. As Aulë rose his great hammer to smite his creations and children forever, he wept, and the Dwarves begged for mercy in fear. Seeing this, Eru decided that their life was valuable and that they should live, but the Dwarves must sleep until it is their time to walk Middle-Earth, so they were granted long life so they could hibernate as time elapsed."
