THE GOLDEN AGE

The early 'Abbasids were also fortunate in the caliber of their caliphs, especially after Harun al-Rashid came to the caliphate in 786. His reign is now the most famous in the annals of the 'Abbasids - partly because of the fictional role given him in The Thousand and One Nights (portions of which probably date from his reign), but also because his reign and those of his immediate successors marked the high point of the 'Abbasid period. As the Arab chronicles put it, Harun al-Rashid ruled when the world was young, a felicitous description of what in later times has come to be called the Golden Age of Islam.
The Golden Age was a period of unrivaled intellectual activity in all fields: science, technology, and (as a result of intensive study of the Islamic faith) literature - particularly biography, history, and linguistics. Scholars, for example, in collecting and reexamining the hadith, or "traditions" - the sayings and actions of the Prophet - compiled immense biographical detail about the Prophet and other information, historic and linguistic, about the Prophet's era. This led to such memorable works as Sirat Rasul Allah, the "Life of the Messenger of God," by Ibn Ishaq, later revised by Ibn Hisham; one of the earliest Arabic historical works, it was a key source of information about the Prophet's life and also a model for other important works of history such as al-Tabari's Annals of the Apostles and the Kings and his massive commentary on the Quran.
