How were the trolls fooled until daylight when they turned to stone?

In J.R.R. Tolkien's "The Hobbit," the trolls were fooled by the cleverness of Bilbo and the dwarves, who took advantage of the trolls' foolishness and lack of intelligence. The trolls were tricked into arguing among themselves about how to cook the dwarves, ultimately delaying their decision until dawn. As the first light of day broke, the trolls were turned to stone, a fate that befell them due to their exposure to sunlight, which revealed their true nature. This clever ruse showcases the theme of wit triumphing over brute strength.
