Ab'ul Hasan Yamīn ud-Dīn Khusrau (1253–1325 CE) (Urdu: ابوالحسن یمین‌الدین خسرو‎) better known as Amīr Khusrow was a Sufi musician, poet and scholar. He was an iconic figure in the cultural history of the Indian subcontinent. He was a mystic and a spiritual disciple of Nizamuddin Auliya of Delhi. Amīr Khusrau is reputed to have invented certain musical instruments like the sitar and tabla. He wrote poetry primarily in Persian, but also in Hindavi. A vocabulary in verse, the Ḳhāliq Bārī, containing Arabic, Persian, and Hindavi terms is often attributed to him.
