Hadith #2

2- عَلِيٌّ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنِ ابْنِ الْمَغْرَاءِ عَنْ إِبْرَاهِيمَ بْنِ مَيْمُونٍ أَنَّهُ سَأَلَ أَبَا عَبْدِ اللهِ (عَلَيْهِ السَّلام) فَقَالَ يُعْطَى الرَّاعِي الْغَنَمَ بِالْجَبَلِ يَرْعَاهَا وَلَهُ أَصْوَافُهَا وَأَلْبَانُهَا وَيُعْطِينَا لِكُلِّ شَاةٍ دَرَاهِمَ فَقَالَ لَيْسَ بِذَلِكَ بَأْسٌ فَقُلْتُ إِنَّ أَهْلَ الْمَسْجِدِ يَقُولُونَ لا يَجُوزُ لأنَّ مِنْهَا مَا لَيْسَ لَهُ صُوفٌ وَلا لَبَنٌ فَقَالَ أَبُو عَبْدِ اللهِ (عَلَيْهِ السَّلام) وَهَلْ يُطَيِّبُهُ إِلا ذَاكَ يَذْهَبُ بَعْضُهُ وَيَبْقَى بَعْضٌ.

2. Ali ibn Ibrahim has narrated from his father from ibn abu ‘Umayr from abu al-Mighra’ from Ibrahim ibn Maymun who has said the following: “This is concerning my question before abu ‘Abd Allah, ‘Alayhi al-Salam, about the case of a shepherd of sheep in the mountains to whom sheep were given to maintain them and use their milk and wool, in addition to a certain amount of dirham for every sheep. He (the Imam) said, ‘It is not unlawful.’ I then said that people of Masjid said, ‘It was not permissible because certain ones among them did not have wool or milk.’ Abu ‘Abd Allah, ‘Alayhi al-Salam, said, ‘Can there be other arrangements better than this? He takes certain ones and leaves others.’”
