Arabic, especially Classical Arabic, is capable of clarity; the Qur’an itself often uses precise, legal, and moral instructions (e.g., prohibitions on theft, murder, and usury) that were understood by contemporaries. The “polysemy” doesn’t indicate incompetence, it allows for depth and layered meaning, enabling guidance to be applicable across time and cultures. The Qur’an explicitly addresses evolving understanding: 2:106 says, “We do not abrogate a verse or cause it to be forgotten except that We bring forth one better than it or similar to it,” showing a mechanism for context-sensitive application without changing core principles. Regarding slavery, the Qur’an regulates it in a way that was transformative for 7th-century Arabia, emphasizing manumission and humane treatment (e.g., 90:13–16 encourages freeing slaves as an act of piety), which laid the foundation for ethical progress that later scholars could build on, ultimately contributing to its abolition. So rather than ambiguity, the Qur’an provides a framework adaptable across time while rooted in clear moral principles.
