I want to know the answer to the following question:
What years did Abbasid caliph Harun ar-Rashid reign?
All the background I'm provided with is that "During the reign of the Abbasid caliph Harun ar-Rashid (786 to 809), the legendary House of Wisdom was inaugurated in Baghdad where scholars from various parts of the world sought to translate and gather all the known world's knowledge into Arabic.". Is that enough to answer the question?
Answer: yes
