Hadith 1148B1

قَالَ مَالِكٌ فِي الْمُمَلَّكَةِ إِذَا مَلَّكَهَا زَوْجُهَا أَمْرَهَا، ثُمَّ افْتَرَقَا، وَلَمْ تَقْبَلْ مِنْ ذَلِكَ شَيْئًا : فَلَيْسَ بِيَدِهَا مِنْ ذَلِكَ شَيْءٌ، وَهُوَ لَهَا مَا دَامَا فِي مَجْلِسِهِمَا
Imam Malik, may Allah have mercy on him, said: In the gathering in which the husband gives the wife the right of divorce, the wife will have the right only in that gathering. If the gathering disperses and the wife has not taken the divorce, then the right will no longer remain.
