Sunan Ibn Majah 2526
The Chapters on Manumission (of Slaves)
Whoever Frees A Slave But Stipulates That He Should Serve Him
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مُعَاوِيَةَ الْجُمَحِيُّ، حَدَّثَنَا حَمَّادُ بْنُ سَلَمَةَ، عَنْ سَعِيدِ بْنِ جُمْهَانَ، عَنْ سَفِينَةَ أَبِي عَبْدِ الرَّحْمَنِ، قَالَ أَعْتَقَتْنِي أُمُّ سَلَمَةَ وَاشْتَرَطَتْ عَلَىَّ أَنْ أَخْدُمَ النَّبِيَّ صلى الله عليه وسلم مَا عَاشَ .
It was narrated from that Safinah - Abu 'Abdur-Rahman-said : “Umm Salamah freed me but stipulated that I should serve the Prophet (ﷺ) as long he lived.”
