Ghubar e Khatir

Ghubar-e-Khatir is one of the most important works of Maulana Abul Kalam Azad

The book is a collection of letters but except one or two letters, all other letters are unique and most of the letters deal with complex issues such as existence of God,[14] the origin of religions, the origin of music and its place in religion, etc. The book is primarily an Urdu language book however there are over five hundreds of couplets, mostly in Persian and Arabic languages. It is because Maulana was born in a family where Arabic and Persian were used more frequently than Urdu. He was born in Mekkah, given formal education in Persian and Arabic languages but he was never taught Urdu. It is often said that his book India wins Freedom is about his political life and Ghubar-e-Khatir deals with his social and spiritual life.
