Saudis rethinking on Tribal traditions of child marriage

Re: Saudis rethinking on Tribal traditions of child marriage

^because you appear to be knowledgeable can i ask something? If a trend is setting where elders are using the premission of child marriages to abuse the rights of children would it be alright to put a ban on it for a while? like i read soemwhere during famine Hazrat Umer r.a banned the penalty for theft (losing a hand).
