ANSWER:

You must do your due diligence by asking around his work place and where he lives and in the masjid he prays in order to gather as much information as possible about him. This is a marriage and not a game.

QUESTION: How can we spy on a potential spouse if they don’t live near our home and it would not be appropriate to ask about their background(job location,friend’s name) and also they might be a sinner in the past but now they have repented and the people who may know the spouse might know about their past only and not their present condition??
