Muwatta Malik #1351
Business Transactions
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، أَنَّ عُبَيْدَ اللَّهِ بْنَ عَبْدِ اللَّهِ بْنِ عُتْبَةَ بْنِ مَسْعُودٍ، أَخْبَرَهُ أَنَّ عَبْدَ اللَّهِ بْنَ مَسْعُودٍ ابْتَاعَ جَارِيَةً مِنِ امْرَأَتِهِ زَيْنَبَ الثَّقَفِيَّةِ وَاشْتَرَطَتْ عَلَيْهِ أَنَّكَ إِنْ بِعْتَهَا فَهِيَ لِي بِالثَّمَنِ الَّذِي تَبِيعُهَا بِهِ فَسَأَلَ عَبْدُ اللَّهِ بْنُ مَسْعُودٍ عَنْ ذَلِكَ عُمَرَ بْنَ الْخَطَّابِ فَقَالَ عُمَرُ بْنُ الْخَطَّابِ لاَ تَقْرَبْهَا وَفِيهَا شَرْطٌ لأَحَدٍ .
Yahya related to me from Malik from Ibn Shihab that Ubaydullah
ibn Abdullah ibn Utba ibn Masud told him that Abdullah ibn Masud
bought a slave-girl from his wife, Zaynab Ath Thaqafiyya. She made a
condition to him, that if he bought her, she could always buy her back
for the price that he paid. Abdullah ibn Masud asked Umar ibn al-
Khattab about that and Umar ibn al-Khattab said, "Do not go near her
while anyone has a condition concerning her over you."
