فَأَمَّا مَا رَوَاهُ مُحَمَّدُ بْنُ عَلِيِّ بْنِ مَحْبُوبٍ عَنِ اَلْهَيْثَمِ بْنِ أَبِي مَسْرُوقٍ اَلنَّهْدِيِّ عَنِ اَلْحَكَمِ بْنِ مِسْكِينٍ عَنْ سَمَاعَةَ قَالَ: قُلْتُ لِأَبِي اَلْحَسَنِ مُوسَى عَلَيْهِ اَلسَّلاَمُ إِنِّي أَبُولُ ثُمَّ أَتَمَسَّحُ بِالْأَحْجَارِ فَيَجِيءُ مِنِّي اَلْبَلَلُ بَعْدَ اِسْتِبْرَائِي مَا يُفْسِدُ سَرَاوِيلِي قَالَ« لَيْسَ بِهِ بَأْسٌ».
Muhammad bin Ali bin Mahbub narrated from Al-Haytham bin Abi Masruq Al-Nahdi, from Al-Hakam bin Miskin, from Sama‘ah, who said:
I said to Abu Al-Hasan Musa عليه السلام: 'I urinate, then I wipe with stones. Afterward, some wetness appears from me following my act of istibra' (ensuring the bladder is emptied), which soils my garment. What should I do?' Imam عليه السلام said: 'There is no harm in it.'"
