WHEN I GO TO PROPOSE A WOMAN FOR MARRIAGE...
Question: When I go to propose a young woman for marriage, how should i speak to her in order to know her Aqeedah, fear of Allaah, manners and etiquettes?
It is permissible for the proposer to have a look at the one he is proposing but not in seclusion, because the Sunnah has confirmed that from the Messenger of Allaah (sallal-laahu-alayhi-wasallam). And he can ask her and her guardians what he holds important in relation to a beneficial marriage.
