Narrated Anas ibn Malik: Allah’s Messenger (salallahu 'alaihi wassalam) said, “He who abandons lying, having been false, will have a castle built for him just within Paradise. He who abandons disputing, having been speaking the truth, will have one built for him in the middle of Paradise. He whose character is good will have one built for him in the highest part of it.” [Tirmidhi transmitted this Hadith, saying this is a hasan tradition. The same is said in Sharh as-Sunnah, but in al-Masabih it is called gharib. - Al-Tirmidhi – Hadith Number 4831].
