If anyone takes a bath on Friday, puts on his best clothes, applies a touch of perfume if has any, then goes to congregational prayer (in the mosque), and takes care not to step over people, then prayer what Allah has prescribes for him, then keeps silent from the time his Imam comes out until he finishes his prayer, it will atone for his sins during the previous week. Abu Hurairah said: (It will atone for his sins) for three days more. he further said: One is rewarded ten times for doing a good work. Abu Dawud said: The version narrated by Muhammad b. Salamah is perfect, and Hammad did not make a mention of the statement of Abu Hurairah.
عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ وَأَبِي هُرَيْرَةَ قَالاَ قَالَ رَسُولُ اللَّهِ ﷺ مَنِ 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 إِذَا خَرَجَ إِمَامُهُ حَتَّى يَفْرُغَ مِنْ صَلاَتِهِ كَانَتْ كَفَّارَةً لِمَا بَيْنَهَا وَبَيْنَ جُمُعَتِهِ الَّتِي قَبْلَهَا قَالَ وَيَقُولُ أَبُو هُرَيْرَةَ وَزِيَادَةُ ثَلاَثَةِ أَيَّامٍ وَيَقُولُ إِنَّ الْحَسَنَةَ بِعَشْرِ أَمْثَالِهَا
