Hadith 2633ـ أَحْمَدُ عَنْ مُوسَى بْنِ الْقَاسِمِ عَنْ إِبْرَاهِيمَ بْنِ عَبْدِ الْحَمِيدِ قَالَ سَأَلْتُ أَبَا الْحَسَنِ (عَلَيْهِ الْسَّلام) عَنِ الثَّوْبِ يُصِيبُهُ الْبَوْلُ فَيَنْفُذُ إِلَى الْجَانِبِ الآخَرِ وَعَنِ الْفَرْوِ وَمَا فِيهِ مِنَ الْحَشْوِ قَالَ اغْسِلْ مَا أَصَابَ مِنْهُ وَمَسَّ الْجَانِبَ الآخَرَ فَإِنْ أَصَبْتَ مَسَّ شَيْءٍ مِنْهُ فَاغْسِلْهُ وَإِلاَّ فَانْضَحْهُ بِالْمَاءِ.
3. Ahmad ibn Musa has narrated from al-Qasim from Ibrahim ibn ‘Abd al-Hamid who has said the following: “I once asked abu al-Hassan (a.s.), about clothes that come in contact with urine and it passes to the other side through its fillings. He (the Imam) said, ‘You must wash the polluted area, feel the other side and wash it clean, if you found something; otherwise, pour water on it to wash it clean.’”
