Fatawa-e-Alamgiri (also known as Al-Fatawa-i-Hindiya in Turkey, Egypt and Syria) is a compilation of law created at instance of the Mughal Emperor Aurangzeb (who was also known as 'Alamgir'). This compilation (or fiqh) is based on Islam's Sharia law, and was the work of many scholars, principally from the Hanafi school.
The Fatawa-e-Alamgiri is notable for several reasons:
It was one of the earliest fiqhs
It spanned 30 volumes, making it the most comprehensive fiqh of its era
It served as the basis of law and doctrine imposed by Aurangzeb throughout his empire
