Whether exploring the thorny issues of wives' sexual duties, divorce, homosexuality, or sex outside marriage, discussions of sexual ethics and Islam often spark heated conflict rather than reasoned argument. In this updated and expanded edition of her ground-breaking work, feminist Muslim scholar Dr Kecia Ali asks how one can determine what makes sex lawful and ethical in the sight of God. Drawing on both revealed and interpretative Muslim texts, Ali critiques medieval and contemporary commentators alike to produce a balanced and comprehensive study of a subject both sensitive and urgent, making this an invaluable resource for students, scholars, and interested readers.
