٤ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ حَمَّادٍ عَنِ الْحَلَبِيِّ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ الْسَّلام) قَالَ إِذَا احْتَلَمَ الرَّجُلُ فَأَصَابَ ثَوْبَهُ شَيْ‏ءٌ فَلْيَغْسِلِ الَّذِي أَصَابَهُ وَإِنْ ظَنَّ أَنَّهُ أَصَابَهُ شَيْ‏ءٌ وَلَمْ يَسْتَيْقِنْ وَلَمْ يَرَ مَكَانَهُ فَلْيَنْضَحْهُ بِالْمَاءِ وَإِنْ يَسْتَيْقِنْ أَنَّهُ قَدْ أَصَابَهُ وَلَمْ يَرَ مَكَانَهُ فَلْيَغْسِلْ ثَوْبَهُ كُلَّهُ فَإِنَّهُ أَحْسَنُ.
4. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from Hammad from al-Halabiy who has said the following: “Abu ‘Abd Allah , has said, ‘If a man experiences wet dream and his clothes come in contact with semen, he must wash the polluted area. If he thinks, but is not certain and has not seen the polluted area, he must pour water on it. If he is certain that semen has come in contact with his clothes but he has not seen the polluted spot, he must wash all of his clothes; it is better.’”
