Is it permissible to propose to a girl when the suitor has no independent source of income, and is it permissible to meet with the fiancée and speak to her with words of love?

There is no objection to proposing to a woman even if the man has no source of income. It is permissible for him to see her face and hands before the engagement. However, after the engagement, it is forbidden to look at her or to be alone with her because she is still a stranger to him until the marriage contract is concluded. It is also not permissible to speak with her about matters that might arouse desire and lead to the forbidden.
