Nakhuda (1981)

When the poor and illiterate Shaikhoo Dada (Kulbhushan Kharbanda) gives up his life savings to bail out Ravi (Raj Kiran) from his financial mess, Ravi begins to revere Shaikhoo as God. Now on the path to success, Ravi marries Soni (Swaroop Sampat) but his rich father-in-law who disapproves of Ravi's affections and respect for a mere commoner starts to create a rift between the two. Knowing the consequences of Ravi rebelling against his rich and powerful father-in-law, Shaikhoo starts to deliberately create circumstances where Ravi will lose all respect for him and move on from this relationship.
