Mehboob Ki Mehndi is a 1971 Indian Hindi-language romantic musical film produced and directed by H. S. Rawail.
She lives with her foster grandmother/ nanny in Bombay, while her mother, Najma stays away from her in Hyderabad with her exploitative partner, Nisaar Ahmed, who is a pimp.
The next day, the young and handsome Yusuf, son of a wealthy royal Nawab Safdarjung who is physically handicapped and uses a wheelchair, comes to Shabana's house.
Firangi's tutor, tired of his mischievous behaviour, throws up her job after he sets a white mouse upon her at Yusuf's instigation.
It was later revealed that Khairuddin's father (Murad) was Nawab Sajjad Hussain whose wealth and family home was seized by Safdarjung 18 years ago, after he was unable to repay a debt.
It was also revealed that Khairuddin had served life imprisonment for killing Najma's step-uncle after she was kicked out of her house on the suspicion that she was going to give birth to an illegitimate child.
Just before their wedding, Shabana gives Khairu a letter which was addressed to Yusuf, revealing that she was the daughter of a courtesan named Najma.
Upon learning of the impending marriage, Nisaar arrives as a servant named Usman to blackmail Shabana into returning to the brothel.
Khairu arrives after hearing her scream and in order to protect her, shoots Nisaar repeatedly as everyone rushed into the room.
