Chapter 61 | Rules about Performing Salah (Prayer) in an Unclean Cloth Regardless One Knows it or Not
8ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ عَلِيِّ بْنِ الْحَكَمِ عَنِ الْعَلاَءِ عَنْ مُحَمَّدِ بْنِ مُسْلِمٍ عَنْ أَحَدِهِمَا (عَلَيْهِما الْسَّلام) قَالَ سَأَلْتُهُ عَنِ الرَّجُلِ يَرَى فِي ثَوْبِ أَخِيهِ دَماً وَهُوَ يُصَلِّي قَالَ لاَ يُؤْذِنُهُ حَتَّى يَنْصَرِفَ.
8. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Ali ibn al-Hakam from al-‘Ala’ from Muhammad ibn Muslim who has said the following: I once asked one of the two Imam, ‘Alayhim al-Salam, about a man who finds blood in clothes of his brother while he is performing Salah (prayer). He (the Imam) said, ‘He is not required to inform him until he completes his Salah (prayer) again.’”
