A Persian physician from Juzjan in Afghanistan (980-1037). He was the closest disciple of Ibn Sīnā. He spent many years with his master in Isfahan, becoming his lifetime companion. Our knowledge of Ibn Sina's life is due in part to the biography composed by al-Juzjani. It is published in English under the title Avicenna, his Life and Work (London, 1958). Gilbert Sinoué took it as a basis for his book Avicenne ou la route d'Ispahan (Paris, 1989).

This biography was translated into Latin by Niccolò Massa as Vita (ipsius) Avicennae ex Sorsano Arabe ejus discipulo in the 16th century.
