||While there are academic scholars who have been studying the perceptions of Muslims about Hinduism and Hindus (Ernst, 2003; Engineer, 2007), there are no academic works which specifically deal with the perceptions of Hindu (mystical) scholars about Islam and Muslims. The purpose of this thesis is to introduce some Hindu scholars from the 19th and early 20th century, who have dealt with Islam and Muslims in their works. This thesis could be used as a framework to explore the Hindu perceptions of Islam and Muslims and therefore as an explanation for the complex relationship between Hindus and Muslims. The thesis will draw on the ideas of: Rammohun Roy (1772 – 1833), Dayananda Sarasvati (better known as Svami Dayananda, 1823/1824 – 1883), Vivekananda (1863 – 1902) and Thanwardas Lilaram Vaswani (better known as Sadhu Vaswani, 1879 – 1966) as sources of inspiration. Vaswani’s thought on Islam and Muslim will shed a new light on the relationship between Hindus and Muslims (for example when we take a look at his personal experiences with both religious communities in Sindh) in the late 19th and early 20th century. Furthermore, Vaswani must be seen as an ‘inclusivist’ Hindu (mystical) scholar who tried to unite Hindus and Muslims not only for a political purpose, but also on a spiritual level.
