Salman Al-Farisi reported: The Prophet, peace and blessings be upon him, said, “No one takes a bath on Friday, purifies himself as much as he can, uses oil or perfume in his house, then proceeds for prayer and does not separate two persons sitting together, then prays as much as is written for him and remains silent while the leader is delivering the sermon, except that his sins between this Friday and the previous will be forgiven.”

عَنْ سَلْمَانَ الْفَارِسِيِّ قَالَ قَالَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ لَا يَغْتَسِلُ رَجُلٌ يَوْمَ الْجُمُعَةِ وَيَتَطَهَّرُ مَا اسْتَطَاعَ مِنْ طُهْرٍ وَيَدَّهِنُ مِنْ دُهْنِهِ أَوْ يَمَسُّ مِنْ طِيبِ بَيْتِهِ ثُمَّ يَخْرُجُ فَلَا يُفَرِّقُ بَيْنَ اثْنَيْنِ ثُمَّ يُصَلِّي مَا كُتِبَ لَهُ ثُمَّ يُنْصِتُ إِذَا تَكَلَّمَ الْإِمَامُ إِلَّا غُفِرَ لَهُ مَا بَيْنَهُ وَبَيْنَ الْجُمُعَةِ الْأُخْرَى
