What is the ruling of Islamic law regarding the bridal gift (mahr) if the woman is divorced before consummation? Is it returned in full or in half?

Upon the mere عقد النكاح (marriage contract), the woman becomes entitled to half of the dower agreed upon (al-mahr al-musamma), including both its advance and deferred portions. This is based on the Almighty's saying: ﴿And if you divorce them before you have touched them and you have already specified for them an obligation (dower) – then for them is half of what you specified.﴾ The full dower is established upon valid seclusion (al-khulwah as-sahihah) or consummation. If there is no consummation or valid seclusion, she is entitled to only half of the dower. In case of dispute, the matter must be referred to the Sharia court.
