[Machine] Two men testified before Ali that a man had committed theft, so Ali cut off the hand of the first man. Then they brought another man and said, "This is the thief, not the first one." Ali then expressed his satisfaction with the testimony of both witnesses and decided to pay the blood money for the severed hand of the first man. He said, "If I had known that you two were lying, I would have cut off both of your hands." This saying is also recorded by Hushaym, and in the narration of Sufyan from Muttarif, they said, "We made a mistake regarding the first man."  

أَنَّ رَجُلَيْنِ شَهِدَا عِنْدَ عَلِيٍّ ؓ عَلَى رَجُلٍ بِالسَّرِقَةِ فَقَطَعَ عَلِيٌّ يَدَهُ ثُمَّ جَاءَا بِآخَرَ فَقَالَا هَذَا هُوَ السَّارِقُ لَا الْأَوَّلُ فَأْغَرَمَ عَلِيٌّ ؓ الشَّاهِدَيْنِ دِيَةَ يَدِ الْمَقْطُوعِ الْأَوَّلِ وَقَالَ لَوْ أَعْلَمُ أَنَّكُمَا تَعَمَّدْتُمَا لَقَطَعْتُ أَيْدِيَكُمَا وَلَمْ يَقْطَعِ الثَّانِيَ لَفْظُ حَدِيثِ هُشَيْمٍ وَفِي رِوَايَةِ سُفْيَانَ عَنْ مُطَرِّفٍ فَقَالَا وَأَخْطَأْنَا عَلَى الْأَوَّلِ  

"عَنِ الشَّعْبِىَّ: أَنَّ رَجُلَيْنِ أَتَيَا عَلِيّا، فَشَهِدَا عَلى رَجُلٍ أَنَّهُ سَرَقَ، فَقَطَعَ يَدَهُ، ثُمَّ أَتَيَاهُ بِآخَر فَقَالَا: هَذَا الَّذِى سَرَقَ وَأَخْطَأَنَا عَلى الأَوَّلِ فلم يُجِزْ شهادتهما على الآخر وَغَرَّمَهُمَا دِيَةَ الأوَّلِ، وَقَالَ: لَوْ أَعَلمُ أَنَّكُما تعَمَّدْتُمَا لَقَطعْتُكُمَا".
