How is the Quranic verse 2:236 understood by Shia scholars where it mentions the possibility of a marriage without a settled dowry? Are there any valid marriage vows in the Twelver School where the dowry is not mentioned?
Salaamun Alaikum
It is possible that they pronounce the permanent marriage contract without mentioning the dowry i.e Mahr, so they can decide on what it will be with a mutual consent after the marriage.
But if the intercourse takes place before determining the dowry, the woman will be eligible to ask for the Mahrul Mesl i.e. a dowry which is usually given to this type of girl with these characteristics and family and social position.
