What is the ruling on designating Friday specifically for sending supplication messages?

Question:
May Allah reward you. This questioner says: My brother sends us messages on his mobile phone every Friday containing supplications for us. Is this permissible?

Answer:
No, my brother, he does not need the mobile phone to supplicate to Allah; he can supplicate to Allah without a mobile phone. He should supplicate to Allah for you without a mobile phone. The mobile phone is for when he wants to greet you, call you, ask you for something, or advise you of something. As for supplication, he should supplicate to Allah directly, without a mobile phone, without anything.
