La faute de grammaire entendue comme mal et le mal de la faute de grammaire dans le Taṯqīf al-lisān de Ibn Makkī al-Ṣiqillī

The Taṯqīf al-lisān wa talqīḥ al-ǧanān by the grammarian and linguist, Abū Ḥafṣ ʿUmar Ibn Ḫalaf Ibn Makkī al-Ḥamīrī al-Māzirī al-Ṣiqillī, is an example of the Arabic language spoken in 10th-century Sicily, when the island was an Islamic Emirate. In its 50 chapters, the treaty lists grammatical errors made by Sicilians whether common people (al-ʿāmma) or cultivated speakers (al-muḫaṣṣiṣūn). The typology of this treatise falls within those classified as laḥn al-ʿāmma, a field of linguistic science that is dedicated to correcting forms that deviate from the grammar rules of the standard language accepted by grammarians and lexicographers. This study will focus on two chapters concerning the incorrectness in the recitation of the Qur’an and in the transmission of aḥādīṯ. The study aims at analyzing the grammatical error concerning the sacred language and the Sunna that can lead to misunderstanding or misinterpretation of Islamic doctrines.
