Ibn el harra.

Jalal is a successful engineer who loves his neighbor Laila, the granddaughter of a pasha, but he hides his love for fear of social differences. Her uncle supervises her money, even though he is a gambler. Laila's cousin, a reckless young man, covets marrying her to seize her money. He learns by chance that Jalal loves Laila, so he tricks them both, and seizes the money from both of them.
