16ـ عَنْهُ عَنْ أَحْمَدَ عَنِ ابْنِ فَضَّالٍ عَنِ ابْنِ بُكَيْرٍ عَنْ بَعْضِ أَصْحَابِنَا عَنْ أَبِي عَبْدِ الله (عَلَيْهِ الْسَّلام) فِي الرَّجُلِ
يَبُولُ وَيَنْسَى أَنْ يَغْسِلَ ذَكَرَهُ حَتَّى يَتَوَضَّأَ وَيُصَلِّيَ قَالَ يَغْسِلُ ذَكَرَهُ وَيُعِيدُ الصَّلاَةَ وَلاَ يُعِيدُ الْوُضُوءَ.
16. Ali ibn Ibrahim has narrated from Muhammad ibn ‘Isa from Yunus from Zur’ah, from Sama‘ah who has said the following:
“Abu ‘Abd Allah 
, has said, ‘After using toilet if you forget to wash clean your buttocks (because of feces) and take Wudu’, then remember after performing Salah (prayer), you must perform your Salah (prayer) again. If you wash your buttocks clean but forget washing your urethra clean and perform Salah (prayer), you must take Wudu’, wash your urethra and perform your Salah (prayer) again. It is because urine is not like feces.’”
