حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَعَبْدُ اللَّهِ بْنُ سَعِيدٍ، قَالاَ حَدَّثَنَا أَبُو خَالِدٍ الأَحْمَرُ، عَنِ ابْنِ عَجْلاَنَ، عَنْ سَعِيدِ بْنِ أَبِي سَعِيدٍ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ ثَلاَثَةٌ كُلُّهُمْ حَقٌّ عَلَى اللَّهِ عَوْنُهُ الْغَازِي فِي سَبِيلِ اللَّهِ وَالْمُكَاتَبُ الَّذِي يُرِيدُ الأَدَاءَ وَالنَّاكِحُ الَّذِي يُرِيدُ التَّعَفُّفَ ‏"‏ ‏.‏

It was narrated from `Amr bin Shu'aib , from his father, from his grandfather that the Messenger of Allah (ﷺ) said

“Any slave who has made a contract to buy his freedom for one hundread Uqiyyah and pays it all except ten Uqiyyah; he is still a slave.” (One Uqiyyah is equal to 40 Dirham.)
