٧ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ عُثْمَانَ بْنِ عِيسَى عَنْ سَمَاعَةَ قَالَ سَأَلْتُ أَبَا عَبْدِ الله (عَلَيْهِ الْسَّلام) عَنِ الرَّجُلِ يَنَامُ وَلَمْ يَرَ فِي نَوْمِهِ أَنَّهُ احْتَلَمَ فَيَجِدُ فِي ثَوْبِهِ وَعَلَى فَخِذِهِ الْمَاءَ هَلْ عَلَيْهِ غُسْلٌ قَالَ نَعَمْ. 
7. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from ‘Uthman ibn ‘Isa from Sama‘ah who has said the following: “I once asked abu ’Abd Allah , about a man who does not experience any wet dream but he finds wet spots on his thigh and his clothes. Is Ghusl (bath) necessary for him? He (the Imam) said, ‘Yes, Ghusl (bath) is necessary.”
