A so far neglected topic of the few academic works on divination in pre-modern Islam is the use and role of anecdotes related to different divinatory practices and experiences in the Islamic literature of the classical period. The aim of this paper is to contribute to fill this void by focusing on Muslim scholars' use of these reports in works regarding the Prophet Muḥammad and, particularly, the dalāʾil al-nubūwa (proofs of prophecy), defined as the literature aiming at proving the prophetic nature of Muḥammad. Recent academic literature has paved the way for such an inquiry. Aḥmad bin Muḥammad Fakīr has identified many works of dalāʾil al-nubūwa and Mareike Koertner has provided one of the first analysis of its genealogy and content in the early centuries of Islam, highlighting as one of its frequent topics the predictions of soothsayers, astronomers, animals, ǧinn and members of Jewish tribes. Building on these works, this paper provides an analysis of H̱ayr al-Bišar bi-H̱ayr al-Bašar (The best of announcements on the best of men) of the Sicilian-born Maliki Ashari scholar Ibn Ẓafar al-Ṣiqillī (1104-1170 ca.). This is structured in four sections: the first one is devoted to announcements of Muḥammad's prophetic mission in different texts of the Jewish and Christian traditions; the second focuses on predictions received or announced by members of different Jewish tribes (ḥabr, pl. aḥbār) before or after the beginning of the Islamic prophecy; the third presents anecdotes regarding soothsayers (kāhin, pl. kuhhān); the fourth part reports anecdotes involving ǧinn.
