Hadith - Unlawful for the Fire

Ibn Mas'ud reported that the Messenger of Allah, may Allah bless him and grant him peace, said, "Shall I tell you who is unlawful for the Fire - or the one for whom the Fire is unlawful? It is unlawful for everyone who is easy, flexible, modest and uncomplicated." [at-Tirmidhi]
