Sunan an-Nasa'i, Book 14, Hadith 1414 (In-Book) ⓘ

It was narrated that Salman said: "The Messenger of Allah said to me: 'There is no man who purifies himself on Friday as he is commanded, then comes out of his house to the Friday prayer, and listens attentively until he finishes his prayer, but it will be an expiation for what came before it the week before."

أَخْبَرَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، قَالَ أَنْبَأَنَا جَرِيرٌ، عَنْ مَنْصُورٍ، عَنْ أَبِي مَعْشَرٍ، زِيَادِ بْنِ كُلَيْبٍ عَنْ إِبْرَاهِيمَ، عَنْ عَلْقَمَةَ، عَنِ الْقَرْثَعِ الضَّبِّيِّ، - وَكَانَ مِنَ الْقُرَّاءِ الأَوَّلِينَ - عَنْ سَلْمَانَ، قَالَ قَالَ لِي رَسُولُ اللَّهِ صلى الله عليه وسلم ‏ "‏ مَا مِنْ رَجُلٍ يَتَطَهَّرُ يَوْمَ الْجُمُعَةِ كَمَا أُمِرَ ثُمَّ يَخْرُجُ مِنْ بَيْتِهِ حَتَّى يَأْتِيَ الْجُمُعَةَ وَيُنْصِتُ حَتَّى يَقْضِيَ صَلاَتَهُ إِلاَّ كَانَ كَفَّارَةً لِمَا قَبْلَهُ مِنَ الْجُمُعَةِ ‏" ‏ ‏.‏
