The Qur’an does not provide the same level of outward detail about every subject. Ambiguous passages, expressions concerning divine attributes, and some details of prophetic narratives require disciplined interpretation.
A narrative can communicate its intended guidance without giving every date, name, or circumstance. Likewise, an expression concerning God should not become a pretext for inventing an unmentioned modality. The interpreter must respect the text and its interpretive limits.
Concision and obscurity differ: a detail may simply be outside the intended subject, whereas obscurity concerns understanding the intended meaning of what is actually said.
