أنس بن مالك
According to Anas ibn Malik, who was one of Muhammad's companions, Muhammad said "Muslims will open a port that is considered the "ability" place, in which the olds of my 'Ummah' will live; a one night in this place is better than a thousand months worship; it is the "ability" place for those who sacrifice their souls for God." Then, Anas said "and what is that "ability" place, Prophet?" Muhammad said "It is the place that is spelled with D, M, and T."
