Chapter 38 | Clothes Come in Contact with Blood and Pus
2ـ أَحْمَدُ عَنْ عُثْمَانَ بْنِ عِيسَى عَنْ سَمَاعَةَ قَالَ سَأَلْتُهُ عَنِ الرَّجُلِ بِهِ الْقَرْحُ أَوِ الْجُرْحُ وَلاَ يَسْتَطِيعُ أَنْ يَرْبِطَهُ وَلاَ يَغْسِلَ دَمَهُ قَالَ يُصَلِّي وَلاَ يَغْسِلُ ثَوْبَهُ كُلَّ يَوْمٍ إِلاَّ مَرَّةً فَإِنَّهُ لاَ يَسْتَطِيعُ أَنْ يَغْسِلَ ثَوْبَهُ كُلَّ سَاعَةٍ.
2. Ahmad has narrated from ‘Uthman ibn ‘Isa from Sama‘ah who has said the following: “I once asked him (the Imam) , about a man on whose body there are sores or wounds which he cannot bandage or wash the blood. He (the Imam) said, ‘He can perform his Salah (prayer) without washing his clothes except once a day; he cannot wash his clothes every hour.’”
