I am a doctor and the girl who i an going to marry is a doctor too. But the girls father works in a bank as a manager and says that he keeps aside some amount of money as interest because he is working in a bank. Can i marry the girl ?

All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.

If you mean by your question that you want to know the ruling on marrying a girl whose father works in a usury-based bank, then, Islamically, there is no impediment to marrying that girl if she is committed to the religion and has a good character. Abu Hurayrah narrated that the Prophet, said: "A woman is married for four (things), her wealth, her lineage status, her beauty and her religion." [Al-Bukhaari]

Therefore, your decision should be based on the girl's religious commitment and character and not that of her parents.

Allah Knows best.
