رُوِيَ عَنْ إِسْحَاقَ بْنِ عَمَّارٍ أَنَّهُ قَالَ: سَأَلَ رَجُلٌ أَبَا عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ وَ أَنَا حَاضِرٌ عَنْ رَجُلٍ ضَرَبَ رَجُلاً فَلَمْ يَنْقَطِعْ بَوْلُهُ قَالَ "إِنْ كَانَ اَلْبَوْلُ يَمُرُّ إِلَى اَللَّيْلِ فَعَلَيْهِ اَلدِّيَةُ وَ إِنْ كَانَ إِلَى نِصْفِ اَلنَّهَارِ فَعَلَيْهِ ثُلُثَا اَلدِّيَةِ وَ إِنْ كَانَ إِلَى اِرْتِفَاعِ اَلنَّهَارِ فَعَلَيْهِ ثُلُثُ اَلدِّيَةِ".
It was narrated from Ishaq ibn Ammar that he said: A man asked Abu Abdullah (a.s), while I was present, about a man who struck another man, causing his urine to flow continuously without stopping. Imam (a.s) said: "If the urine continues until the night, then the full blood money (diyyah) is due. If it continues until midday, then two-thirds of the blood money is due. If it continues only until the morning rises, then one-third of the blood money is due."
