رَوَى اَلْحَسَنُ بْنُ مَحْبُوبٍ عَنْ عَبْدِ اَللَّهِ بْنِ سِنَانٍ قَالَ سَمِعْتُ أَبَا عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ يَقُولُ كَانَ أَمِيرُ اَلْمُؤْمِنِينَ عَلَيْهِ اَلسَّلاَمُ يَقُولُ: إِنَّ اَلنَّاسَ كُلَّهُمْ أَحْرَارٌ إِلاَّ مَنْ أَقَرَّ عَلَى نَفْسِهِ بِالرِّقِّ وَ هُوَ مُدْرِكٌ مِنْ عَبْدٍ أَوْ أَمَةٍ وَ مَنْ شَهِدَ عَلَيْهِ شَاهِدَانِ بِالرِّقِّ صَغِيراً كَانَ أَوْ كَبِيراً.
Al-Hasan ibn Mahbub narrated from 'Abdullah ibn Sinan, who said: "I heard Abu Abdullah (a.s) say: Commander of the Faithful, peace be upon him, used to say: 'Indeed, all people are free, except for the one who acknowledges servitude upon himself while being of sound understanding-whether he is a slave or a bondwoman-or the one upon whom two witnesses testify to his servitude, whether he is young or old.'"
