Hadith 1157
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ يَحْيَى بْنِ سَعِيدٍ، عَنِ الْقَاسِمِ بْنِ مُحَمَّدٍ، . أَنَّ رَجُلاً، كَانَتْ تَحْتَهُ وَلِيدَةٌ لِقَوْمٍ فَقَالَ لأَهْلِهَا شَأْنَكُمْ بِهَا . فَرَأَى النَّاسُ أَنَّهَا تَطْلِيقَةٌ وَاحِدَةٌ .
Yahya related to me from Malik from Yahya ibn Said from al-Qasim ibn Muhammad that a certain man had taken a slave-girl belonging to somebody else as a wife. He said to her people, "She is your concern," and people considered that to be one pronouncement of divorce
