Al-Biruni’s Kitab-ul-Hind was written in Arabic.
Al-Biruni was a Central Asian scholar who travelled to India with Mahmud of Ghazni in the early 11th century. His monumental work, Kitab-ul-Hind (literally “Book on India”), is a comprehensive study of Indian society, culture, religion, philosophy, science, and geography. Al-Biruni wrote this work, like most of his scholarly output, in Arabic.
Al-Biruni learned Sanskrit to study Indian texts and interact with local scholars. His work stands out for its objective and scholarly approach to understanding a foreign culture, making it an invaluable source for the history of medieval India. Arabic was the prominent language of scholarship across the Islamic world during that period.
