3ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ مُحَمَّدِ بْنِ الْحُسَيْنِ عَنْ عُثْمَانَ بْنِ عِيسَى عَنْ أَبِي الْمَغْرَاءِ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ الْسَّلام) قَالَ إِنَّ الله تَبَارَكَ وَتَعَالَى أَشْرَكَ بَيْنَ الأغْنِيَاءِ وَالْفُقَرَاءِ فِي الأمْوَالِ فَلَيْسَ لَهُمْ أَنْ يَصْرِفُوا إِلَى غَيْرِ شُرَكَائِهِمْ.

3. Muhammad ibn Yahya has narrated from Muhammad ibn al-Husayn from ‘Uthman ibn ‘Isa from abu al-Maghra’ who has said the following: “Abu ‘Abd Allah, ‘Alayhi al-Salam, has said, ‘Allah, most Blessed, most High, has made the affluent to share their wealth with the needy people; thus, they must not share it with others (affluent ones).”’
