Hasan said in explanation of this hadith (A man begins his morning a believer and turns a disbeliever in the evening, or begins his evening as a believer and turns a disbeliever in the morning). He said, Morning finds him holding the blood, honour and property of his brother sacred (and disallawed to him), but by evening he will regard them as lawful to him. And evening finds him holding his brothers blood, honour and property as sacred (and forbidden to him), but by morning he regards them as lawful to him.
