In the second situation, when the woman's dower has been fixed before marriage and divorce occurs before actual consummation, the injunction says that the man shall be obligated to pay half of the dower already fixed. However, should the woman forgive, or should the man pay the whole, this will be a matter of free choice, as is evident from the verse:
إِلَّا أَن يَعْفُونَ أَوْ يَعْفُوَ الَّذِي بِيَدِهِ عُقْدَةُ النِّكَاحِ
Unless they (the women) forgive, or forgives the one in whose hand lies the marriage tie. (2:237)
The use of the word ya` fu يَعْفُوَ ('forgives' ) to cover even the payment of full dower, perhaps, reflects the customary Arab practice of the payment of dower amount simultaneously with the marriage. If so, the husband has become, in the event of a pre-consummation divorce, deserving of taking half of the dower back. Now, if he yields voluntarily and does not take his half back, this too, would virtually be an act of forgiving. And the act of forgiving has been declared more merit-worthy, and closer to Tagwa (the sense of being responsible to Allah, commonly rendered as piety or fear or righteousness in absence of an exact equivalent); because this forgiveness symbolically indicates that the severance of the bond of marriage was also done with magnanimity and good grace, which is the objective of the Shari'ah and certainly, deserving of great merit -- the forgiveness could come from the woman, or from the man, it does not matter.
Explaining the words of the verse الَّذِي بِيَدِهِ عُقْدَةُ النِّكَاحِ whose hands lies the marriage tie), the Holy Prophet ﷺ has himself said: ولی عُقْدَةُ النِّكَاحِ , that is, 'the husband is the guardian (wali) of the bond of marriage.' This hadith appears in Darqutni as narrated by ` Amr ibn Shu'ayb from his father on the authority of his grandfather, and also from Sayyidna ` Aii ؓ and Sayyidna ibn ` Abbas ؓ (Qurtubi).
This also proves that the authority to continue or terminate the bond of marriage rests with the husband. It is he who can pronounce talaq (divorce). The woman cannot divorce her husband.
