3238 - وَ رُوِيَ عَنْ عَلِيٍّ عَلَيْهِ اَلسَّلاَمُ أَنَّهُ قَالَ قَالَ رَسُولُ اَللَّهِ صَلَّى اَللَّهُ عَلَيْهِ وَ آلِهِ : "إِذَا تَقَاضَى إِلَيْكَ رَجُلاَنِ فَلاَ تَقْضِ لِلْأَوَّلِ حَتَّى تَسْمَعَ مِنَ اَلْآخَرِ فَإِنَّكَ إِذَا فَعَلْتَ ذَلِكَ تَبَيَّنَ لَكَ اَلْقَضَاءُ " قَالَ عَلِيٌّ عَلَيْهِ اَلسَّلاَمُ "فَمَا زِلْتُ بَعْدَهَا قَاضِياً" وَ قَالَ لَهُ اَلنَّبِيُّ صَلَّى اَللَّهُ عَلَيْهِ وَ آلِهِ " اَللَّهُمَّ فَهِّمْهُ اَلْقَضَاءَ ".
Hadith.3238 - It is narrated from Imam Ali ibn Abi Talib (as) that Imam (as) said: The Messenger of Allah (swt) (peace be upon him and his family) said: "If two men bring a case before you, do not judge in favor of the first until you hear from the other, for if you do so, the judgment will become clear to you." Imam Ali ibn Abi Talib (as) said: "After that, I continued to serve as a judge." And the Prophet (peace be upon him and his family) said to him: "O Allah (swt), grant him understanding in judgment."
