6ـ عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ سَهْلِ بْنِ زِيَادٍ عَنِ ابْنِ مَحْبُوبٍ عَنِ ابْنِ رِئَابٍ عَنِ الْحَلَبِيِّ عَنْ أَبِي عَبْدِ الله (عَلَيهِ السَّلام) قَالَ لا بَأْسَ بِذِكْرِ الله وَأَنْتَ تَبُولُ فَإِنَّ ذِكْرَ الله عَزَّ وَجَلَّ حَسَنٌ عَلَى كُلِّ حَالٍ فَلا تَسْأَمْ مِنْ ذِكْرِ الله.
6. A number of our people have narrated from Sahl ibn Ziyad from ibn Mahbub from ibn Ri’ab from al-Halabi from Abu ‘Abdillah (a.s.) who has said the following: “Abu ‘Abd Allah (a.s.) has said, ‘It is not an offense to speak of Allah when you are urinating; speaking of Allah, the Most Majestic, the Most Holy, is good in all conditions. Do not feel embarrassed about it.’”
