2- مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ مُحَمَّدِ بْنِ خَالِدٍ عَنْ سَعْدِ بْنِ سَعْدٍ عَنْ مُحَمَّدِ بْنِ الْقَاسِمِ بْنِ الْفُضَيْلِ عَنْ أَبِي الْحَسَنِ (عَلَيْهِ السَّلام) قَالَ سَأَلْتُهُ قُلْتُ لَهُ رَجُلٌ مِنْ مَوَالِيكَ عَلَيْهِ دَيْنٌ لِرَجُلٍ مُخَالِفٍ يُرِيدُ أَنْ يَعْسُرَهُ وَيَحْبِسَهُ وَقَدْ عَلِمَ أَنَّهُ لَيْسَ عِنْدَهُ وَلا يَقْدِرُ عَلَيْهِ وَلَيْسَ لِغَرِيمِهِ بَيِّنَةٌ هَلْ يَجُوزُ لَهُ أَنْ يَحْلِفَ لَهُ لِيَدْفَعَهُ عَنْ نَفْسِهِ حَتَّى يُيَسِّرَ اللهُ لَهُ وَإِنْ كَانَ عَلَيْهِ الشُّهُودُ مِنْ مَوَالِيكَ قَدْ عَرَفُوا أَنَّهُ لا يَقْدِرُ هَلْ يَجُوزُ أَنْ يَشْهَدُوا عَلَيْهِ قَالَ لا يَجُوزُ أَنْ يَشْهَدُوا عَلَيْهِ وَلا يَنْوِيَ ظُلْمَهُ.

2. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Muhammad ibn Khalid from Sa‘d ibn Sa‘d from Muhammad ibn al-Qasim ibn al-Fudayl who has narrated the following: “I once asked abu al-Hassan, ‘Alayhi al-Salam, about a man who is one of his followers and owes to a Mukhalif (opposing) man a certain amount of loan who wants to cause him difficulties and imprison him. He knows that he does not have anything to pay and he is not able to pay but his creditor has no proof, if it is permissible to swear to keep him away from himself until Allah grants him ease and if it is permissible to testify against him. He (the Imam) said, Tt is not permissible to testify against him when he is not intending to be unjust to him.’”
