Whoever Frees A Slave But Stipulates That He Should Serve Him

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.”

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 ﷺ مَا عَاشَ .
