What is the ruling on communicating privately between a sister and her wali (no mahram)? When the information exchanged is private, how should the communication be between them? May Allah reward you with goodness.
Shaikh Hasan Al-Banna says:
She can ask a friend of her to make her husband (her friend’s husband) to be an intermediate between her and the Walee.
So she tells her friend whatever she wants say to him, and her friend tells her husband to convey the message to the Walee.
In case of private personal matters, then she can communicate directly but within strict limits and according to islam regulation in order to avoid Fitnah.
