Innovating Within Tradition: Ethical Boundaries in Sharia (Bidʿa) and Halakha (Hiddush), and the Challenge of Secular Modernity

This paper explores the ethical aspects of religious innovation by benchmarking the Islamic idea of Bidʿa with the Jewish concept of Hiddush, all within the larger framework of secular modernity. It pulls from classical jurisprudence, theological discussions, and contemporary reformist views to explore how both traditions manage to stay true to divine law while also navigating the challenges and opportunities that change brings. The Qur’an emphasizes divine originality and creativity, stating: “[Allah is] the Originator of the heavens and the earth” (Badiʿ al-samāwāt wa-al-arḍ, Qur’an 2:117). This verse is often referenced to underscore the theological validity of embracing novelty when it aligns with divine intent. In a similar vein, Rabbinic tradition values interpretive renewal, as Nachmanides points out: “It is an obligation imposed upon us to search through the subjects of the Torah and the precepts and bring to light their hidden contents” (Nachmanides, Commentary on the Torah). By viewing secularism as a crucial lens, the paper sheds light on the challenges faced by traditional authority structures, interpretive limits, and moral legitimacy in our diverse and intellectually free age. Ultimately, it presents a thoughtful framework for understanding sacred innovation—not just as a departure or advancement, but as an ethically charged negotiation between maintaining continuity and embracing renewal.
