What is the religious ruling on a father refusing to walk his bride-daughter to the wedding car?

Weighing customs by the scales of Islamic law is the basis for determining what is acceptable and what is rejected at weddings. Whatever contravenes the Sharia is to be discarded, and whatever does not contradict it is permissible. A father accompanying his daughter to the car on her wedding night is not against the Sharia, unless the custom of the land deems it disgraceful. In that case, the father may refrain from doing so to avoid stigma, because custom is considered in Islamic rulings.
