The Grand Ayatollah Safi’s answer to a question about marrying those with Haram incomes

The Grand Ayatollah Safi: But marrying a person whose job is Haram and his income is Haram, although intrinsically it is not forbidden, that is also of those marriages which will not be enjoyable for Muslim woman; because a Muslim must avoid Haram food, clothes and properties, and living with such a husband becomes difficult, unless before marriage, the husband leaves the Haram job and chooses a Halal and legitimate job. May God keep you and all the Muslim ladies steadfast  in the way of Islam, modesty and Hijab.
