When a Soul Becomes Corrupted

Imām Ibn Taimiyyah, may Allāh have mercy on him, said:

When a person’s soul or temperament becomes corrupted, he craves what harms him, and he takes pleasure in [that]; in fact, he will love that so intensely that it will ruin his mind, his religion, his character and manners, his body, and his wealth and property.
