Hadith 713491 - وَ رَوَى اَلْعَلاَءُ عَنْ مُحَمَّدِ بْنِ مُسْلِمٍ عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ : فِي قَوْلِ اَللَّهِ عَزَّ وَ جَلَّ:
فَكٰاتِبُوهُمْ إِنْ عَلِمْتُمْ فِيهِمْ خَيْراً قَالَ "اَلْخَيْرُ أَنْ يَشْهَدَ أَنْ لاَ إِلَهَ إِلاَّ اَللَّهُ وَ أَنَّ مُحَمَّداً رَسُولُ اَللَّهِ وَ يَكُونَ بِيَدِهِ عَمَلٌ يَكْتَسِبُ بِهِ أَوْ يَكُونَ لَهُ حِرْفَةٌ".
Hadith.3491 - Al-Ala' narrated from Muhammad ibn Muslim, from Abu Abdullah (as), regarding the saying of Allah (swt), the Mighty and Majestic:
"Then write [a contract of emancipation] for them if you know any good in them" (Surah An-Nur 24:33).
Imam (as) said: "The 'good' refers to bearing witness that there is no god but Allah (swt) and that Muhammad is the Messenger of Allah (swt), and that the slave possesses a skill by which he can earn a livelihood or has a trade."
