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. (Using translation from Abū Dāʾūd 343)
عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ وَأَبِي هُرَيْرَةَ قَالَا قَالَ رَسُولُ اللهِ ﷺ مَنْ اغْتَسَلَ يَوْمَ الْجُمُعَةِ وَاسْتَاكَ وَمَسَّ مِنْ طِيبٍ إِنْ كَانَ عِنْدَهُ وَلَبِسَ مِنْ أَحْسَنِ ثِيَابِهِ ثُمَّ خَرَجَ حَتَّى يَأْتِيَ الْمَسْجِدَ فَلَمْ يَتَخَطَّ رِقَابَ النَّاسِ ثُمَّ رَكَعَ مَا شَاءَ أَنْ يَرْكَعَ ثُمَّ أَنْصَتَ إِذَا خَرَجَ الْإِمَامُ فَلَمْ يَتَكَلَّمْ حَتَّى يَفْرُغَ مِنْ صَلَاتِهِ كَانَتْ كَفَّارَةً لِمَا بَيْنَهَا وَبَيْنَ الْجُمُعَةِ الَّتِي قَبْلَهَا قَالَ وَكَانَ أَبُو هُرَيْرَةَ يَقُولُ وَثَلَاثَةُ أَيَّامٍ زِيَادَةٌ إِنَّ اللهَ جَعَلَ الْحَسَنَةَ بِعَشْرِ أَمْثَالِهَا
