عَنْهُ عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ أَبِي نَصْرٍ عَنْ عَبْدِ اَلْكَرِيمِ عَنِ اَلْحُسَيْنِ بْنِ حَمَّادٍ عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ قَالَ:« إِذَا أَحَسَّ اَلرَّجُلُ أَنَّ بِثَوْبِهِ بَلَلاً وَ هُوَ يُصَلِّي فَلْيَأْخُذْ ذَكَرَهُ بِطَرَفِ ثَوْبِهِ فَيَمْسَحُهُ بِفَخِذِهِ فَإِنْ كَانَ بَلَلاً يَعْرِفُ فَلْيَتَوَضَّأْ وَ لْيُعِدِ اَلصَّلاَةَ وَ إِنْ لَمْ يَكُنْ بَلَلاً فَذَلِكَ مِنَ اَلشَّيْطَانِ»
From him, from Ahmad ibn Muhammad from Ahmad ibn Muhammad ibn Abi Nasr from Abdul-Karim from al-Husayn ibn Hammad:
Abu Abdillah عليه السلام, peace be upon him, said: "If a man senses moisture on his garment while he is praying, then let him take hold of his private part with the edge of his garment and wipe it against his thigh. If it turns out to be a moisture he recognizes (actual impurity), then let him perform ablution and repeat the prayer. But if it is not a known moisture, then that is from Shaytan."
