23ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ حَمَّادٍ عَنْ حَرِيزٍ عَنْ زُرَارَةَ وَحَدِيدٍ قَالاَ قُلْنَا لأَبِي عَبْدِ الله (عَلَيْهِ الْسَّلام)
السَّطْحُ يُصِيبُهُ الْبَوْلُ أَوْ يُبَالُ عَلَيْهِ أَ يُصَلَّى فِي ذَلِكَ الْمَكَانِ فَقَالَ إِنْ كَانَ تُصِيبُهُ الشَّمْسُ وَالرِّيحُ وَكَانَ جَافّاً فَلاَ بَأْسَ بِهِ إِلاَّ أَنْ يَكُونَ يُتَّخَذُ مَبَالاً.
23. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad, from Hammad from Hariz from Zurarah and Ali ibn Hadid who have said the following:
“We once asked abu ‘Abd Allah 
, about a roof on which there is urine. Can one perform Salah (prayer) there? He (the Imam) said, ‘If sun rays and wind can reach it and it is dry, there is no offense in it unless it is used as a urinating place.’”
