٤ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ مُحَمَّدِ بْنِ الْحُسَيْنِ عَنْ عَلِيِّ بْنِ الْحَكَمِ عَنِ الْعَلاَءِ بْنِ رَزِينٍ عَنْ مُحَمَّدِ بْنِ مُسْلِمٍ عَنْ أَحَدِهِمَا (عَلَيْهِما الْسَّلام) قَالَ سَأَلْتُهُ عَنِ الرَّجُلِ يَبُولُ وَلَمْ يَمَسَّ يَدَهُ شَيْ‏ءٌ أَ يَغْمِسُهَا فِي الْمَاءِ قَالَ نَعَمْ وَإِنْ كَانَ جُنُباً.
4. Muhammad ibn Yahya has narrated from Muhammad ibn al-ffusayn, from Ali ibn al-Hakam, from ‘Ala’ ibn Razin, from Muhammad ibn Muslim who has said the following: “I once asked one of the two Imam, ‘Alayhim al-Salam, about a man who urinates but does not touch anything, must he wash it with water? He (the Imam) said, ‘Yes, if he has experienced sexual relation.’”
