٤ـ أَبُو دَاوُدَ عَنِ الْحُسَيْنِ بْنِ سَعِيدٍ عَنْ أَخِيهِ الْحَسَنِ عَنْ زُرْعَةَ عَنْ سَمَاعَةَ قَالَ سَأَلْتُهُ عَنِ الرَّجُلِ يُجْنِبُ ثُمَّ يَغْتَسِلُ قَبْلَ أَنْ يَبُولَ فَيَجِدُ بَلَلاً بَعْدَ مَا يَغْتَسِلُ قَالَ يُعِيدُ الْغُسْلَ وَإِنْ كَانَ بَالَ قَبْلَ أَنْ يَغْتَسِلَ فَلاَ يُعِيدُ غُسْلَهُ وَلَكِنْ يَتَوَضَّأُ وَيَسْتَنْجِي. 
4. Abu Dawud has narrated from al-Husayn ibn Sa‘id from his brother, al-Hassan from Zur’ah from Sama‘ah who has said the following: “I once asked the Imam about a man who experiences sexual relation; then takes Ghusl (bath) before urinating and finds wet spots after Ghusl (bath). He (the Imam) said, ‘He must take Ghusl (bath) again. Had he urinated before Ghusl (bath), he did not have to take Ghusl (bath) again; but he must take Wudu’ and cleanse himself properly.’”
