Muwatta Malik #1179
Marriage
The Arabic includes the chain of narration (sanad) and the collector's commentary; the English translation shows the Prophet's words only.
حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنِ ابْنِ شِهَابٍ، عَنْ أَبِي عَبْدِ الرَّحْمَنِ، عَنْ زَيْدِ بْنِ ثَابِتٍ، أَنَّهُ كَانَ يَقُولُ فِي الرَّجُلِ يُطَلِّقُ الأَمَةَ ثَلاَثًا ثُمَّ يَشْتَرِيهَا إِنَّهَا لاَ تَحِلُّ لَهُ حَتَّى تَنْكِحَ زَوْجًا غَيْرَهُ .
Yahya related to me from Malik from Ibn Shihab from Abu Abd ar-
Rahman that Zayd ibn Thabit said that if a man divorced his slave-girl
three times and then bought her, she was not halal for him until she
had married another husband.
