al-Raghib composes the Mufradat alfaz al-Qur'an among his Qur'anic monographs, early 5th/11th century

al-Raghib al-Isfahani compiled his alphabetical lexicon Mufradat alfaz al-Qur'an, the clearest display of his predilection for subtle semantic analysis; its influence can still be traced in tafsir and in the lexicons of Qur'anic vocabulary ¹.

In the Mufradat's introduction al-Raghib mentions two earlier works of his — the Risala munabbiha 'ala fawa'id al-Qur'an and the Risala fi'l-qawanin al-dalla 'ala tahqiq munasabat al-alfaz, both apparently lost — and promises a book on the obscure distinctions between apparent synonyms in the Qur'an, probably the Durrat al-ta'wil fi mutashabih al-tanzil ¹.

No source dates the composition precisely; it is placed tentatively within his activity in the early fifth century before his death ¹.
