From his father, from his grandfather that he heard the Messenger of Allah ﷺ delivering a Khutbah in which he said: "Whoever gives a writ of emancipation to his slave, for one hundred Uqiyyah, and he pays it to him less then ten Uqiyah." - or he said: "Ten Dirham" - "then he becomes incapable (of paying the remainder), the he remains a slave."  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَخْطُبُ يَقُولُ مَنْ كَاتَبَ عَبْدَهُ عَلَى مِائَةِ أُوقِيَّةٍ فَأَدَّاهَا إِلاَّ عَشْرَ أَوَاقٍ أَوْ قَالَ عَشَرَةَ دَرَاهِمَ ثُمَّ عَجَزَ فَهُوَ رَقِيقٌ  

“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.)  

قَالَ رَسُولُ اللَّهِ ﷺ أَيُّمَا عَبْدٍ كُوتِبَ عَلَى مِائَةِ أُوقِيَّةٍ فَأَدَّاهَا إِلاَّ عَشْرَ أُوقِيَّاتٍ فَهُوَ رَقِيقٌ  

“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.) (Using translation from Ibn Mājah 2519)  

قَالَ رَسُولُ اللهِ ﷺ أَيُّمَا عَبْدٍ كُوتِبَ عَلَى مِائَةِ أُوقِيَّةٍ فَأَدَّاهَا إِلَّا عَشْرَ أَوَاقٍ فَهُوَ رَقِيقٌ

قَالَ رَسُولُ اللهِ ﷺ «أَيُّمَا عَبْدٍ كُوتِبَ عَلَى مِائَةِ وُقِيَّةٍ فَأَدَّاهَا إِلَّا عَشْرَ أَوَاقٍ ثُمَّ عَجَزَ فَهُوَ رَقِيقٌ»  

"مَنْ كَاتَبَ مَمْلوُكَهُ عَلَى مِائَةِ أُوقِيَةٍ فأدَّاهَا إِلا عَشْرَ أَوَاقٍ ثُمَّ عَجَزَ فهُوَ رقِيقٌ".
