Wadia's relationship with her father became strained when she expressed her desire to marry the Parsi-born Indian Neville Wadia. Jinnah, a Muslim, tried to dissuade her, but failed. M. C. Chagla, who was Jinnah's assistant at the time, recalls: "Jinnah, in his usual imperious manner, told her that there were millions of Muslim boys in India, and she could have chosen anyone. Reminding her father that his wife (Dina's mother Rattanbai), had also been a non-Muslim and a Parsi as well, the young lady replied: 'Father, there were millions of Muslim girls in India. Why did you not marry one of them?'" "And he replied that, 'She became a Muslim'."
