إِنَّمَا شِفَاءُ الْعِيِّ السُّؤَالُ
The remedy for not knowing is to ask.
Source: أبو داود
شِفَاءُ means “remedy,” الْعِيِّ refers here to not knowing or being unable to resolve a matter, and السُّؤَالُ means “asking.” An appropriate question addressed to a knowledgeable person can correct an error before it grows.
إِنَّمَا expresses restriction or emphasis on the remedy. شِفَاءُ الْعِيِّ is an iḍāfah, “the remedy for not knowing”; شِفَاءُ is the subject and السُّؤَالُ the predicate of the nominal sentence.
The report also teaches intellectual humility: admitting that one does not know is a starting point for reliable learning.
