Hadith #14

14ـ مُحَمَّدُ بْنُ إِسْمَاعِيلَ عَنِ الْفَضْلِ بْنِ شَاذَانَ عَنْ صَفْوَانَ بْنِ يَحْيَى عَنْ عَبْدِ الرَّحْمَنِ بْنِ الْحَجَّاجِ قَالَ قُلْتُ لأَبِي الْحَسَنِ (عَلَيْهِ الْسَّلام) رَجُلٌ مُسْلِمٌ مَمْلُوكٌ وَمَوْلاَهُ رَجُلٌ مُسْلِمٌ وَلَهُ مَالٌ يُزَكِّيهِ وَلِلْمَمْلُوكِ وَلَدٌ صَغِيرٌ حُرٌّ أَ يُجْزِئُ مَوْلاَهُ أَنْ يُعْطِيَ ابْنَ عَبْدِهِ مِنَ الزَّكَاةِ فَقَالَ لاَ بَأْسَ بِهِ.

14. Muhammad ibn ’Isma‘il has narrated from al-Fadl ibn Shadhan from Safwan ibn Yahya from ‘Abd al-Rahman ibn al-Hajjaj who has said the following: “I once asked abu al-Hassan, ‘Alayhi al-Salam, about a man who is a Muslim and a slave and his owner is a Muslim man and he has a certain amount of asset from which he pays Zakat. The slave has a small child who is free. Can the master pay Zakat to the child of his slave? He (the Imam) said, ‘It is not harmful.’”
