أَخْبَرَنَا نُوحُ بْنُ حَبِيبٍ، قَالَ أَنْبَأَنَا عَبْدُ الرَّزَّاقِ، قَالَ أَنْبَأَنَا مَعْمَرٌ، عَنِ الزُّهْرِيِّ، عَنْ سَالِمٍ، عَنْ أَبِيهِ، أَنَّ النَّبِيَّ صلى الله عليه وسلم قَالَ " مَنْ أَعْتَقَ شِرْكًا لَهُ فِي عَبْدٍ أُتِمَّ مَا بَقِيَ فِي مَالِهِ إِنْ كَانَ لَهُ مَالٌ يَبْلُغُ ثَمَنَ الْعَبْدِ " .
