Tafsir Ibn Kathir -> Surah Al-Baqarah -> 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.

﴿وَإِن طَلَّقْتُمُوهُنَّ مِن قَبْلِ أَن تَمَسُّوهُنَّ وَقَدْ فَرَضْتُمْ لَهُنَّ فَرِيضَةً فَنِصْفُ مَا فَرَضْتُمْ إَّلآ أَن يَعْفُونَ أَوْ يَعْفُوَاْ الَّذِى بِيَدِهِ عُقْدَةُ النّكَاحِ وَأَن تَعْفُواْ أَقْرَبُ لِلتَّقْوَى وَلاَ تَنسَوُاْ الْفَضْلَ بَيْنَكُمْraster)30%,p(=Rrgjim"ت ث ج ح خ -﴾

(237. And if you divorce them before you have touched (had a sexual relation with) them, and you have appointed for them their due (dowry), then pay half of that, unless they (the women) agree to remit it, or he (the husband), in whose hands is the marriage tie, agrees to remit it. And to remit is nearer to At-Taqwa (piety, righteousness). And do not forget liberality between yourselves. Truly, Allah is All-Seer of what you do.)
