question #2 Sahih al-Bukhari 6474, Book 81, Hadith 63 : How does safeguarding one’s tongue and private parts relate to the promise of Paradise?

Allah’s Messenger (ﷺ) said, “Whoever can guarantee (the chastity of) what is between his two jaw-bones and
what is between his two legs (i.e. his tongue and his private parts), I guarantee Paradise for him.”
