Narrated Abu Shuraih: The Prophet said, "By Allah, he does not believe! By Allah, he does not believe! By Allah, he does not believe!" It was said, "Who is that, O Allah's Apostle?" He said, "That person whose neighbor does not feel safe from his evil."
— Sahih Bukhari, Volume 8, Book 73: Good Manners and Form (Al-Adab), Hadith #45
