Abu 'Ubayd al-Juzjani
He was the famous pupil of Avicenna, whom he first met in Gorgan. He spent many years with his master in Isfahan, becoming his lifetime companion. After Avicenna's death, he completed Avicenna's Autobiography with a concluding section.
The historician Ibn Abi Usaibia refers Avicenna and his close companion Abu Ubayd lived together the residence of Sheikh al-Raiss (which is the title given to Avicenna) and were used to pass each night on studying one by one the Canon and Shifā's instructions.
