The Prophet ﷺ 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."  

قَالَ النَّبِيُّ ﷺ 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  

I said to Ibn ʿAbbas, "The people are narrating that the Prophet ﷺ said, 'Take a bath on Friday and wash your heads (i.e. take a thorough bath) even though you were not Junub and use perfume'." On that Ibn ʿAbbas replied, "I know about the bath, (i.e. it is essential) but I do not know about the perfume (i.e. whether it is essential or not.)  

أَنَّ النَّبِيَّ ﷺ قَالَ اغْتَسِلُوا يَوْمَ الْجُمُعَةِ وَاغْسِلُوا رُءُوسَكُمْ وَإِنْ لَمْ تَكُونُوا جُنُبًا وَأَصِيبُوا مِنَ الطِّيبِ قَالَ ابْنُ عَبَّاسٍ أَمَّا الْغُسْلُ فَنَعَمْ وَأَمَّا الطِّيبُ فَلاَ أَدْرِي  

Ibn ʿAbbas mentioned the statement of the Prophet ﷺ regarding the taking of a bath on Friday and then I asked him whether the Prophet ﷺ had ordered perfume or (hair) oil to be used if they could be found in one's house. He (Ibn ʿAbbas) replied that he did not know about it.  

أَنَّهُ ذَكَرَ قَوْلَ النَّبِيِّ ﷺ فِي الْغُسْلِ يَوْمَ الْجُمُعَةِ فَقُلْتُ لاِبْنِ عَبَّاسٍ أَيَمَسُّ طِيبًا أَوْ دُهْنًا إِنْ كَانَ عِنْدَ أَهْلِهِ فَقَالَ لاَ أَعْلَمُهُ
