Is it appropriate for someone to be asking a girl in the mosque to get to know her for marriage? I mean like actually going up to her an asking or is this considered not appropriate? I don’t know why but although the person is in a mosque environment, I saw it as ‘ayb for someone to just come up and ask like that. It would be more appropriate if an intermediary person but would the first scenario still be deemed not appropriate?

Yes there needs to be some etiquette and protocol to take steps in reference to asking for someone in marriage
