Salam alaikum! I am getting married soon insha allah. The girl's father is separated from her mom. And for personal reasons cant state why. But he isn't involved in her life and has been for 15 years now. She has two young brothers both mature.
Now the question is. Do I still need to get in touch with her father to ask permission even though he won't pick up the phone? My mum is insisting that we must get in touch with him otherwise the marriege won't be valid.
I just wanted some islamic answer to know how to tackle this matter through the sunnah.
