Abu'l Hasan Yamīn ud-Dīn Khusrau (1253–1325 AD), better known as Amīr Khusrau Dehlavī, was an Indo-Persian Sufi singer, musician, poet and scholar who lived under the Delhi Sultanate. 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, India. 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. Khusrau is sometimes referred to as the "voice of India" or "Parrot of India" (Tuti-e-Hind), and has been called the "father of Urdu literature."
