14ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنِ ابْنِ أُذَيْنَةَ عَنْ زُرَارَةَ قَالَ تَوَضَّأْتُ يَوْماً وَلَمْ أَغْسِلْ ذَكَرِي ثُمَّ صَلَّيْتُ فَسَأَلْتُ أَبَا عَبْدِ الله (عَلَيْهِ الْسَّلام) فَقَالَ اغْسِلْ ذَكَرَكَ وَأَعِدْ صَلاَتَكَ.
14. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from ibn ’Udhaynah from Zurarah who has said the following: “One day I performed ablution (wudu’), but I didn't wash my urethra, then I prayed. So I asked abu ‘Abdillah عليه السلام about it. He said: “Wash your urethra and repeat your prayer.“
