889. hadíth
وَ سُئِلَ اَلصَّادِقُ عَلَيْهِ اَلسَّلاَمُ عَنْ مُكَاتَبٍ عَجَزَ عَنْ مُكَاتَبَتِهِ وَ قَدْ أَدَّى بَعْضَهَا قَالَ "يُؤَدَّى عَنْهُ مِنْ مَالِ اَلصَّدَقَةِ إِنَّ اَللَّهَ عَزَّ وَ جَلَّ يَقُولُ فِي كِتَابِهِ: وَ فِي اَلرِّقٰابِ ".
Imam Jafar ibn Muhammad Al-Sadiq (a.s) was asked about a mukatab (a slave under a contract of emancipation) who was unable to complete the payments of his contract, although he had already paid part of it. Imam (a.s) said: "The remaining amount should be paid on his behalf from the charity funds, as Allah (swt), the Mighty and Majestic, says in His (swt) Book: 'and for freeing slaves' (Surah At-Tawbah 9:60)."
