٣- عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ مُحَمَّدِ بْنِ عِيسَى عَنْ يُونُسَ عَمَّنْ رَوَاهُ قَالَ اسْتِخْرَاجُ الْحُقُوقِ بِأَرْبَعَةِ وُجُوهٍ بِشَهَادَةِ رَجُلَيْنِ عَدْلَيْنِ فَإِنْ لَمْ يَكُنْ رَجُلَيْنِ عَدْلَيْنِ فَرَجُلٌ وَامْرَأَتَانِ فَإِنْ لَمْ تَكُنِ امْرَأَتَانِ فَرَجُلٌ وَيَمِينُ الْمُدَّعِي فَإِنْ لَمْ يَكُنْ شَاهِدٌ فَالْيَمِينُ عَلَى الْمُدَّعَى عَلَيْهِ فَإِنْ لَمْ يَحْلِفْ [وَ] رَدَّ الْيَمِينَ عَلَى الْمُدَّعِي فَهُوَ وَاجِبٌ عَلَيْهِ أَنْ يَحْلِفَ وَيَأْخُذَ حَقَّهُ فَإِنْ أَبَى أَنْ يَحْلِفَ فَلا شَيْ‏ءَ لَهُ.
3. Ali ibn Ibrahim has narrated from Muhammad ibn ‘Isa from Yunus from the one who narrated to him who has narrated the following: “He (the Imam) , has said, ‘There are four ways to prove a case. One way to prove it is the testimony of two just men, if this is not available, then one man and two women, if this is not available, then it is the testimony of one man and the oath of the plaintiff; if there is no witness then the oath is on the defendant. If the defendant does not take the oath and turns it to plaintiff then it is obligatory on him to take the oath to receive his right, and if he declines, there is nothing for him.’”
