He is known for writing the earliest treatise on Arabic grammar, through study of the Quran, explaining why he is sometimes known as the "Father of Arabic Grammar." ad-Du'alī is said to have introduced the use of diacritics (consonant and vowel markings) to writing, and to have written the earliest treatises on Arabic linguistics, and grammar (nahw).
