Question: When did Ibn al-Rumi's early biography write his works about Al-Rumi? Passage:Abu al-Hasan Ali ibn al-Abbas ibn Jurayj (), also known as Ibn al-Rumi (born Baghdad in 836; died 896), was the grandson of George the Greek (Juraij or Jurjis i.e. Georgius) and a popular poet of Baghdad in the Abbasid-era. By the age of twenty he earned a living from his poetry. His many political patrons included the Tahirid ruler Ubaydallah ibn Abdallah ibn Tahir, Abbasid caliph Al-Mu'tamid's minister the Persian Isma'il ibn Bulbul, and the politically influential Nestorian family Banu Wahb. He was a Shiite with Mutazilite leanings. He died of illness at the age of 59. His early biographer Ibn Khallikan relates an account that he was given poisoned biscuits in the presence of the caliph Al-Mu'tadid on the orders of his vizier, Al-Qasim ibn Ubayd Allah, whom Ibn al-Rumi had satirised viciously. In another account his death is attributed to suicide. In the tenth-century his Diwan (collected poetry), that had been transmitted orally by al-Mutanabbi, was arranged and edited by Abu Bakr ibn Yahya al-Suli, and included in the section of his book Kitab Al-Awraq () on muhadathun (modern poets).
