وَ مَا رَوَاهُ مُحَمَّدُ بْنُ اَلْحَسَنِ اَلصَّفَّارُ عَنْ مُحَمَّدِ بْنِ عِيسَى عَنْ أَحْمَدَ بْنِ هِلاَلٍ قَالَ: سَأَلْتُهُ عَنْ رَجُلٍ اِغْتَسَلَ قَبْلَ أَنْ يَبُولَ فَكَتَبَ« أَنَّ اَلْغُسْلَ بَعْدَ اَلْبَوْلِ إِلاَّ أَنْ يَكُونَ نَاسِياً فَلاَ يُعِيدُ مِنْهُ اَلْغُسْلَ».
Narrated by Muhammad ibn al-Hasan al-Saffar, from Muhammad ibn Isa, from Ahmad ibn Hilal, who said:
I asked Imam عليه السلام about a man who performed ghusl before urinating, and Imam عليه السلام wrote: "Ghusl should be performed after urination, except if he forgets. In that case, he does not need to repeat the ghusl."
