15ـ عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ الْحُسَيْنِ بْنِ سَعِيدٍ عَنْ فَضَالَةَ عَنْ عَبْدِ الله بْنِ سِنَانٍ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ الْسَّلام) قَالَ اغْتَسَلَ أَبِي مِنَ الْجَنَابَةِ فَقِيلَ لَهُ قَدْ أَبْقَيْتَ لُمْعَةً فِي ظَهْرِكَ لَمْ يُصِبْهَا الْمَاءُ فَقَالَ لَهُ مَا كَانَ عَلَيْكَ لَوْ سَكَتَّ ثُمَّ مَسَحَ تِلْكَ اللُّمْعَةَ بِيَدِهِ.
15. A number of our people have narrated from Ahmad ibn Muhammad from al-Husayn ibn Sa‘id from Fadalah from ‘Abdillah ibn Sinan from Abu ‘Abdillah (a.s.) who said, "Once my father took a major Ghusl (bath performed because of sexual relation or discharge of semen)." Someone said to him, "A spot is left on your back which water has not reached." He (the Imam) said to him, “It was not necessary for you (to inform me). (I wish) you remained quiet.” He then wiped that spot with his hand.’”
