Nakhuda (1981)

Ravi Shankar lives in a shabby hotel room belonging to the owner of the Hotel "Allah Belli", Sheikhu Dada. Ravi studies in college and pays his rent and living expenses through money-orders sent to him from his dad. Ravi's devotion to the illiterate Shaikhoo Dada borders on worship, which doesn't sit well with his wife or her father, wealthy tycoon Seth Jaghannadh. When Seth drives a wedge between Ravi and Dada, Ravi risks everything to make things right.
