Tahdhīb al-Aḥkām|Volume 1|Book 1|Chapter 6
اَلْحُسَيْنُ بْنُ سَعِيدٍ عَنْ أَخِيهِ اَلْحَسَنِ عَنْ زُرْعَةَ عَنْ سَمَاعَةَ قَالَ: سَأَلْتُهُ عَنِ اَلرَّجُلِ يُجْنِبُ ثُمَّ يَغْتَسِلُ قَبْلَ أَنْ يَبُولَ فَيَجِدُ بَلَلاً بَعْدَ مَا يَغْتَسِلُ قَالَ« يُعِيدُ اَلْغُسْلَ فَإِنْ كَانَ بَالَ قَبْلَ أَنْ يَغْتَسِلَ فَلاَ يُعِيدُ غُسْلَهُ وَ لَكِنْ يَتَوَضَّأُ وَ يَسْتَنْجِي».
Narrated by al-Husayn ibn Sa'id, from his brother al-Hasan, from Zur'ah, from Sama'ah, who said:
I asked Imam عليه السلام about a man who becomes junub and then performs ghusl before urinating, and afterward finds wetness. Imam عليه السلام said: "He must repeat the ghusl. However, if he had urinated before performing ghusl, he does not need to repeat the ghusl but should perform wudu and cleanse himself (istinja)."
