my mother بارك الله فيها has been speaking to a sister and she asked my important questions do you recommend to ask questions when meeting her or just to look at her and have further conversation with her dad? if so what should I ask and or advice on the type of questions to ask? بارك الله فيكم

Ask her yourself, in the presence of her wali, and speak normally about her religion and her manners, her education and work, how she spends her free time and who she takes knowledge from, and let the akhlaq show itself in the conversation. Speaking to her father is in addition to that and not a replacement for it, and for the family itself you ask those who know them. Also make sure she is compatible with you, so that you do not end up marrying a woman who wants to travel a lot and go out a lot when you hate that, and this is just an example and you understand what I mean in shā' Allah.
