عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ وَأَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُمَا قَالَا: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ: ((مَنِ اغْتَسَلَ يَوْمَ الْجُمُعَةِ وَاسْتَأْكَ وَمَسَّ مِنْ طِيبٍ إِنْ كَانَ عِنْدَهُ وَلَبِسَ مِنْ أَحْسَنِ ثِيَابِهِ ثُمَّ خَرَجَ حَتَّى يَأْتِيَ الْمَسْجِدَ فَلَمْ يَتَخَطَّ رِقَابَ النَّاسِ حَتَّى 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 زِيَادَةً إِنَّ اللَّهَ جَعَلَ الْحَسَنَةَ بِعَشْرِ أَمْثَالِهَا
It is narrated from Sayyiduna Abu Sa'id Khudri and Sayyiduna Abu Hurairah (may Allah be pleased with them) that the Messenger of Allah (peace and blessings be upon him) said: Whoever performs ghusl on Friday, uses miswak, applies perfume if he has it, wears his best clothes, then goes out and comes to the mosque and does not step over people's necks, then prays as much as he wishes, and when the Imam comes, he remains silent and does not speak until the prayer is finished, then this (Friday) will be an expiation for the sins committed between this Friday and the previous Friday. Sayyiduna Abu Hurairah (may Allah be pleased with him) said: It also becomes an expiation for three more days (of sins), because Allah Almighty has made one good deed equal to ten times its like.
