Muwatta Malik, 1294

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

Oubaidallah Ibn Abdallah Ibn Outba Ibn Mass'oud a raconté que Abdallah Ibn Mass'oud s'est acheté une esclave de sa femme Zainab Al-Thaqafia, qui la lui donna à condition de la lui revendre au même prix qui sera proposé le jour de la vente, Abdallah Ibn Mass'oud demanda à ce sujet, Omar Ibn Al-Khattab qui lui dit: «tu ne pourras pas toucher cette esclave, du moment que sa vente est soumise à une condition»
