714. hadíth
وَ رَوَى اَلْحَسَنُ بْنُ مَحْبُوبٍ عَنِ اَلْعَلاَءِ عَنْ مُحَمَّدِ بْنِ مُسْلِمٍ عَنْ أَبِي جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ قَالَ: "تَجُوزُ شَهَادَةُ اَلْمَمْلُوكِ مِنْ أَهْلِ اَلْقِبْلَةِ عَلَى أَهْلِ اَلْكِتَابِ ".
And it was narrated by Al-Hasan ibn Mahbub, from Al-Ala', from Muhammad ibn Muslim, from Abu Ja'far Imam Muhammad ibn Ali Al-Baqir (a.s), who said: "The testimony of a slave from the people of the Qiblah (Muslims) is valid against the People of the Book (Jews and Christians)."
