Al-Baqarah 2:236
لَّا جُنَاحَ عَلَيْكُمْ إِن طَلَّقْتُمُ النِّسَاءَ مَا لَمْ تَمَسُّوهُنَّ أَوْ تَفْرِضُوا لَهُنَّ فَرِيضَةً ۚ وَمَتِّعُوهُنَّ عَلَى الْمُوسِعِ قَدَرُهُ وَعَلَى الْمُقْتِرِ قَدَرُهُ مَتَاعًا بِالْمَعْرُوفِ ۖ حَقًّا عَلَى الْمُحْسِنِينَ ٢٣٦
La junaha AAalaykum in tallaqtumu alnnisaa ma lam tamassoohunna aw tafridoo lahunna fareedatan wamattiAAoohunna AAala almoosiAAi qadaruhu waAAala almuqtiri qadaruhu mataAAan bialmaAAroofi haqqan AAala almuhsineena
There is no fault in you, if you divorce women while as yet you have not touched them nor appointed any marriage-portion for them; yet make provision for them, the affluent man according to his means, and according to his means the needy man, honourably -- an obligation on the good-doers. (2:236)
Divorce before consummating the Marriage
Allah allowed divorce after the marriage contract and before consummating the marriage. Ibn `Abbas, Tawus, Ibrahim and Al-Hasan Al-Basri said that `touched' (mentioned in the Ayah) means sexual intercourse. The husband is allowed to divorce his wife before consummating the marriage or giving the dowry if it was deferred.
The Mut`ah (Gift) at the time of Divorce
Allah commands the husband to give the wife (whom he divorces before consummating the marriage) a gift of a reasonable amount, the rich according to his means and the poor according to his means, to compensate her for her loss. Al-Bukhari reported in his Sahih that Sahl bin Sa`d and Abu Usayd said that Allah's Messenger married Umaymah bint Sharahil. When she was brought to the Prophet he extended his hand to her, but she did not like that. The Prophet then ordered Abu Usayd to provide provisions for her along with a gift of two garments.
