Relationships Before Islam

What happens when someone becomes muslim whilst they’re in a relationship with someone; such as being married, having a long term partner, or having a boyfriend or girlfriend? This person could be someone they love very dearly and care for. They may have been with eachother for many years, or even have children together. Does it mean that because one of them has become muslim and the other hasn’t, that eveything comes to an end? The relationship’s over and they have to seperate or divorce? Or can they still be together, living their lives as they did before? This episode is based on Ibn Qayyim’s work ‘Ahkam Ahl al-Dhimma’ as well as religious verdicts of contemporary scholars.
