٣- مُحَمَّدُ بْنُ يَحْيَى عَنْ مُحَمَّدِ بْنِ الْحُسَيْنِ عَنْ مُوسَى بْنِ سَعْدَانَ عَنِ الْحُسَيْنِ بْنِ أَبِي الْعَلاءِ عَنْ إِسْحَاقَ بْنِ عَمَّارٍ عَنْ أَبِي الْحَسَنِ (عَلَيْهِ السَّلام) قَالَ سَأَلْتُهُ عَنِ الرَّجُلِ يَكُونُ لَهُ عَلَى رَجُلٍ مَالٌ قَرْضاً فَيُعْطِيهِ الشَّيْ‏ءَ مِنْ رِبْحِهِ مَخَافَةَ أَنْ يَقْطَعَ ذَلِكَ عَنْهُ فَيَأْخُذَ مَالَهُ مِنْ غَيْرِ أَنْ يَكُونَ شَرَطَ عَلَيْهِ قَالَ لا بَأْسَ بِذَلِكَ مَا لَمْ يَكُنْ شَرْطاً. 
3. Muhammad ibn Yahya has narrated from Muhammad ibn al-Husayn from Musa ibn Sa‘dan from al-Husayn ibn abu al-‘Ala’ from Ishaq ibn ‘Ammar who has said the following: “I once asked abu al-Hassan, Alayhi al-Salam, about the case of a man who is a debtor and pays a certain amount out of his profit to his creditor for fear of the creditor’s demand for payment, but there is no such condition between them. He (the Imam) said, ‘It is not harmful as long as it is not a condition.’”
