Papyrology Nabia Abbott's concentration was in Arabic and Islamic studies. The Oriental Institute had a large collection of early Islamic papyri and documents on paper and parchment. Abbott published these documents and helped expand the Institute's collection. Abbott published an essay in 1949 about a 9th-century fragment of the Arabian Nights, which contains the title and first page of the works. She demonstrated its assistance in elucidating early Arabic palaeography as well as the development of early Islamic books in paper. She proved it was nearly a century older than earliest known references to the Arabian Nights, and established a chronology of the evolution of the Arabian Nights, which has remained valid since then.
Hadiths Early generations of Western scholars of Islam, notably
Ignác Goldziher and
Joseph Schacht, had introduced a scepticism to the
hadith tradition, which - as actions or habits by the
Muhammad - was supposedly the basis for Islamic Law. They claimed that these originated, instead, in the first few centuries of Islam (therefore, not contemporaneous with Muhammad), and that these were attempts to shoehorn authority atop a legal foundation that had already been laid. Indeed, the hadith had been traditionally held to be of higher consequence than the opinions of Muhammad's successors or companions, and over time, the desire to promote certain laws over others resulted in the attribution of Successors' arguments to the Companions, and the Companions' opinions to Muhammad himself. Nabia Abbott, on the other hand, argued that hadith was an original practice in Islam, held in written form until they entered the canonical books. In answer to the question of the unavailability of these early manuscripts, she blamed the
Caliph Umar, who ordered the destruction of these writings to prevent a parallel development of holy literature that might contend against the
Qur'an. After his death, however, the remaining hadiths compiled by some of the Muhammad's companions, formed the basis of the later collections. ==Selected works==
