Sahih Bukhari Volume 2, Book 11, Hadith 884

حَدَّثَنَا آدَمُ، قَالَ حَدَّثَنَا ابْنُ أَبِي ذِئْبٍ، عَنْ سَعِيدٍ الْمَقْبُرِيِّ، قَالَ أَخْبَرَنِي أَبِي، عَنِ ابْنِ وَدِيعَةَ، عَنْ سَلْمَانَ الْفَارِسِيِّ، قَالَ قَالَ النَّبِيُّ صلى الله عليه وسلم ‏"‏ لاَ يَغْتَسِلُ رَجُلٌ يَوْمَ الْجُمُعَةِ، وَيَتَطَهَّرُ مَا اسْتَطَاعَ مِنْ طُهْرٍ، وَيَدَّهِنُ مِنْ دُهْنِهِ، أَوْ يَمَسُّ مِنْ طِيبِ بَيْتِهِ ثُمَّ يَخْرُجُ، فَلاَ يُفَرِّقُ بَيْنَ اثْنَيْنِ، ثُمَّ يُصَلِّي مَا كُتِبَ لَهُ، ثُمَّ يُنْصِتُ إِذَا تَكَلَّمَ الإِمَامُ، إِلاَّ غُفِرَ لَهُ مَا بَيْنَهُ وَبَيْنَ الْجُمُعَةِ الأُخْرَى ‏"

Narrated By Salman-Al-Farsi : The Prophet (p.b.u.h) said, "Whoever takes a bath on Friday, purifies himself as much as he can, then uses his (hair) oil or perfumes himself with the scent of his house, then proceeds (for the Jumua prayer) and does not separate two persons sitting together (in the mosque), then prays as much as (Allah has) written for him and then remains silent while the Imam is delivering the Khutba, his sins in-between the present and the last Friday would be forgiven."
