Abu Sa'id and Abu Huraira reported God’s Messenger as saying, “If anyone bathes on a Friday, puts on his best clothes, applies a touch of perfume if he has any, then goes to the congregational prayer and takes care not to step over people, then prays what God has prescribed for him, then keeps silent from the time his imam comes out till he finishes his prayer, it will atone for his sins during the previous week." Abu Dawud transmitted it.

عَنْ أَبِي سَعِيدٍ وَأَبِي هُرَيْرَةَ قَالَا: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «من اغْتَسَلَ يَوْمَ الْجُمُعَةِ وَلَبِسَ مِنْ أَحْسَنِ ثِيَابِهِ وَمَسَّ مِنْ طِيبٍ إِنْ كَانَ عِنْدَهُ ثُمَّ أَتَى الْجُمُعَةَ فَلَمْ يَتَخَطَّ أَعْنَاقَ النَّاسِ ثُمَّ صَلَّى مَا كَتَبَ اللَّهُ لَهُ ثُمَّ أَنْصَتَ إِذا خرج إِمَام حَتَّى يَفْرُغَ مِنْ صَلَاتِهِ كَانَتْ كَفَّارَةً لِمَا بَيْنَهَا وَبَيْنَ جُمُعَتِهِ الَّتِي قَبْلَهَا» . رَوَاهُ أَبُو دَاوُد
