Sharḥ gharīb al-Qurʾān explains words and expressions whose lexical or idiomatic force is not immediately familiar to the reader. It assists Qur’anic interpretation but does not replace the larger work of tafsīr.
A careful explanation examines the core sense, attested Arabic usage, an appropriate translation, and the fit of the meaning within the verse. The task is not simply to list dictionary possibilities but to establish which sense is intended.
An unfamiliar word is not automatically a doctrinally ambiguous verse; conversely, knowledge of a dictionary gloss does not remove the need for historical or rhetorical context.
