٤- مُحَمَّدُ بْنُ يَحْيَى عَنْ مُحَمَّدِ بْنِ الْحُسَيْنِ عَنْ صَفْوَانَ عَنْ يَعْقُوبَ بْنِ شُعَيْبٍ قَالَ سَأَلْتُ أَبَا عَبْدِ اللهِ (عَلَيْهِ السَّلام) عَنِ الرَّجُلِ يُقْرِضُ الرَّجُلَ الدَّرَاهِمَ الْغِلَّةَ فَيَأْخُذُ مِنْهُ الدَّرَاهِمَ الطَّازَجِيَّةَ طَيِّبَةً بِهَا نَفْسُهُ فَقَالَ لا بَأْسَ وَذَكَرَ ذَلِكَ عَنْ عَلِيٍّ (عَلَيْهِ السَّلام).
4. Muhammad ibn Yahya has narrated from Muhammad ibn al-Husayn from Safwan from Ya’qub ibn Shu’ayb who has said the following: “This is concerning my question before abu ‘Abd Allah , about the case of a man who gave impure dirhams as a loan to another man, who then paid him back with better dirhams without compulsion. He (the Imam) said, it is not unlawful and it is from Ali .’”
