The Guru Granth Sahib , is a collection of hymns of the first five `` Sikh Gurus '' , the `` Ninth Guru '' , and various saints . Though Sri Guru Granth Sahib Ji contains the compositions of both Sikh Gurus as well the other great saints ( Bhagats ) â '' including those of the Hindu and Muslim faithâ '' no distinction whatsoever is made between the works of Sikh Gurus and the works of the Bhagats contained within the Siri Guru Granth Sahib ; the titles `` Guru '' and `` Bhagat '' should not be misleading .
