عَنْهُ عَنْ عُثْمَانَ بْنِ عِيسَى عَنْ سَمَاعَةَ قَالَ سَأَلْتُهُ عَنْ كَلْبِ الصَّيْدِ يُمْسَكُ فِي الدَّارِ قَالَ إِذَا كَانَ يُغْلَقُ دُونَهُ الْبَابُ فَلَا بَأْسَ .

6. It is narrated from the narrator of the previous Hadith from ‘Uthman ibn ‘Isa from Sama‘ah who has said the following: “I once asked him (the Imam), ‘Alayhi al-Salam, if a hunting dog can be kept in the house. He (the Imam) said, ‘If a door can be closed in front of it, then it is not harmful.’”
