Some slaves came out to the Messenger of Allah ﷺ on the day of Hudaybiyyah, before the truce was concluded. Their masters wrote to him saying, "Muhammad, by Allah, they have not come out to you out of any desire for your religion. They have only fled to escape slavery."Some people said, "They have spoken the truth, Messenger of Allah. Send them back to their masters."The Messenger of Allah ﷺ became angry and said, "I do not see you stopping, people of Quraysh, until Allah sends against you someone who will strike your necks over this matter."He refused to return them and said, "They are the freedmen of Allah ."
حدثنا عبد العزيز بن يحيى الحراني حدثني محمد يعني ابن سلمة عن محمد بن إسحق عن أبان بن صالح عن منصور بن المعتمر عن ربعي بن حراش
خرج عبدان إلى رسول الله ﷺ يعني يوم الحديبية قبل الصلح فكتب إليه مواليهم فقالوا يا محمد والله ما خرجوا إليك رغبة في دينك وإنما خرجوا هربا من الرق فقال ناس صدقوا يا رسول الله ردهم إليهم فغضب رسول الله ﷺ وقال ما أراكم تنتهون يا معشر قريش حتى يبعث الله عليكم من يضرب رقابكم على هذا وأبى أن يردهم وقال هم عتقاء الله عز وجل
[Its chain of transmission is daif] Hakim reported it, 2/125, from the hadith of Abdul-Aziz bin Yahya, transmitting it in this manner, and he graded it sahih according to the criterion of Muslim, and Dhahabi agreed with him. Tirmidhi also narrated it, no. 3715, from the hadith of Sharik the judge, from Mansur, transmitting it in this manner, and he said, hasan sahih gharib. Muhammad bin Ishaq and Sharik the judge are both mudallis narrators, and they narrated it using "an" (without explicit statement of direct hearing).
