Muwatta Malik, Book 29, Hadith 45 (USC-MSA)

Yahya related to me from Malik that he had heard that Abd ar- Rahman ibn Awf divorced his wife, and gave her compensation in the form of a slave-girl.

حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، أَنَّهُ بَلَغَهُ أَنَّ عَبْدَ الرَّحْمَنِ بْنَ عَوْفٍ، طَلَّقَ امْرَأَةً لَهُ فَمَتَّعَ بِوَلِيدَةٍ ‏.‏

Yahya related to me from Malik from Nafi that Abdullah ibn Umar said, "Every divorced woman has compensation except for the one who is divorced and is allocated a bride-price and has not been touched. She has half of what was allocated to her."

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ نَافِعٍ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ، أَنَّهُ كَانَ يَقُولُ لِكُلِّ مُطَلَّقَةٍ مُتْعَةٌ إِلاَّ الَّتِي تُطَلَّقُ وَقَدْ فُرِضَ لَهَا صَدَاقٌ وَلَمْ تُمَسَّ فَحَسْبُهَا نِصْفُ مَا فُرِضَ لَهَا ‏.‏
