Ab'ul Hasan Yamīn ud-Dīn Khusrow (1253–1325 CE) (Urdu: ابوالحسن یمینالدین خسرو; Hindi: अबुल हसन यमीनुद्दीन ख़ुसरौ), better known as Amīr Khusrow (also Khusrau, Khusro) Dehlawī (meaning Amir Khusrow of Delhi) (امیر خسرو دہلوی; अमीर ख़ुसरौ दहलवी), was an Indian musician, scholar and poet. He was an iconic figure in the cultural history of the Indian subcontinent. A Sufi mystic and a spiritual disciple of Nizamuddin Auliya of Delhi, Amīr Khusrow was not only a notable poet but also a prolific and seminal musician. He wrote poetry primarily in Persian, but also in Hindavi. He compiled the oldest known printed dictionary (Khaliq-e-bari) in 1320 which mainly dealt with Hindvi (Hindi) and Persian words.
