Is it permissible to propose to a girl after seeing her by chance in front of the institute once, and then asking for her father's address?

A Muslim should frequently supplicate and ask Allah Almighty for a righteous wife, and avoid methods of searching for a wife that lead to falling into শরীয়াহ prohibitions, such as uncontrolled gazing and suspicious situations. For this purpose, there are legitimate means, including seeking help from trustworthy relatives and friends.
