What is the ruling on marrying a fiancé who works in cigarette marketing, knowing that he has recently become religious and promised to look for another job? Should this religious girl agree to him?

We do not advise marriage to someone who works in tobacco marketing because their earnings are unlawful (khabith). If your relative insists on marrying him, she may stipulate that he leave this job, and she should not eat from or benefit from his unlawful earnings except out of necessity.
