In which one of the following works did Amir Khusrau praise the climate of India, its language (mainly Sanskrit), its art and music and even its animals ?

Nuh Sipihr (Nine Skies), composed by Amir Khusrau in 1318 during the reign of Mubarak Shah Khalji, contains lavish praise of India — its climate, languages (especially Sanskrit which he called the best of all languages), arts and music, flowers, fruits, animals, and people. The work consists of nine chapters (sipihrs) and is a remarkable expression of Khusrau's deep love for his homeland. Ijaz-e Khusravi is a prose work on rhetoric, Deval Rani Khizr Khani is a romantic mathnavi, and Khazainul Futuh is a historical account of Alauddin Khalji's conquests.
