In the name of Allah, the Gracious, the Merciful
Al-Nawawi recorded in his book Riyad al-Salihin:
Allah Almighty said:
فَإِذَا قُضِيَتِ الصَّلَاةُ فَانتَشِرُوا فِي الْأَرْضِ وَابْتَغُوا مِن فَضْلِ اللَّهِ وَاذْكُرُوا اللَّهَ كَثِيرًا لَّعَلَّكُمْ تُفْلِحُونَ
When the prayer has been concluded, then disperse within the land and seek from the bounty of Allah and remember Allah often that you may succeed.
Surat al-Jumuah 62:10
Abu Huraira reported: The Messenger of Allah, peace and blessings be upon him, said:
خَيْرُ يَوْمٍ طَلَعَتْ عَلَيْهِ الشَّمْسُ يَوْمُ الْجُمُعَةِ فِيهِ خُلِقَ آدَمُ وَفِيهِ أُدْخِلَ الْجَنَّةَ وَفِيهِ أُخْرِجَ مِنْهَا وَلَا تَقُومُ السَّاعَةُ إِلَّا فِي يَوْمِ الْجُمُعَةِ
The best day on which the sun has risen is Friday. Adam was created on Friday and on it he entered Paradise and on it he was expelled from therein. The Hour will not be established but on Friday.

Abu Huraira reported: The Messenger of Allah, peace and blessings be upon him, said:
مَنْ تَوَضَّأَ فَأَحْسَنَ الْوُضُوءَ ثُمَّ أَتَى الْجُمُعَةَ فَاسْتَمَعَ وَأَنْصَتَ غُفِرَ لَهُ مَا بَيْنَهُ وَبَيْنَ الْجُمُعَةِ وَزِيَادَةُ ثَلَاثَةِ أَيَّامٍ وَمَنْ مَسَّ الْحَصَى فَقَدْ لَغَا
Whoever performs ablution in an excellent manner, comes to Friday prayer, and listens while remaining quiet, his sins will be forgiven until the next Friday and an additional three days, but whoever plays with pebbles has behaved frivolously.

Taking a bath on Friday is a duty upon every person who has reached the age of puberty.

Samurah ibn Jundab reported: The Messenger of Allah, peace and blessings be upon him, said:
مَنْ تَوَضَّأَ يَوْمَ الْجُمُعَةِ فَبِهَا وَنِعْمَتْ وَمَنْ اغْتَسَلَ فَالْغُسْلُ أَفْضَلُ
Whoever performs ablution on Friday has done well, and whoever performs a ritual bath has done better.
Al-Shafi’i, may Allah have mercy on him, commented on this tradition:
The command of the Prophet to perform a ritual bath on Friday indicates preference for it, not an obligation.

Salman al-Farisi reported: The Messenger of Allah, peace and blessings be upon him, said:
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
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.

فِيهِ سَاعَةٌ لَا يُوَافِقُهَا عَبْدٌ مُسْلِمٌ وَهُوَ قَائِمٌ يُصَلِّي يَسْأَلُ اللَّهَ تَعَالَى شَيْئًا إِلَّا أَعْطَاهُ إِيَّاهُ
In it is an hour in which no Muslim stands to pray and ask Allah for something but that he will be given it.

Abu Burdah reported: Abdullah ibn Umar said to me, “Have you heard anything narrated by your father from the Messenger of Allah, peace and blessings be upon him, about the special moment on Friday?” I said: Yes. I heard him narrate that the Prophet said:
هِيَ مَا بَيْنَ أَنْ يَجْلِسَ الْإِمَامُ إِلَى أَنْ تُقْضَى الصَّلَاةُ
It is the moment between the beginning of the sermon and the completion of the prayer.

Aws ibn Aws reported: The Messenger of Allah, peace and blessings be upon him, said:
إِنَّ مِنْ أَفْضَلِ أَيَّامِكُمْ يَوْمَ الْجُمُعَةِ فِيهِ خُلِقَ آدَمُ وَفِيهِ قُبِضَ وَفِيهِ النَّفْخَةُ وَفِيهِ الصَّعْقَةُ فَأَكْثِرُوا عَلَيَّ مِنْ الصَّلَاةِ فِيهِ فَإِنَّ صَلَاتَكُمْ مَعْرُوضَةٌ عَلَيَّ
Verily, the best of your days is Friday. Adam was created on it, on it he died, on it the trumpet will be blown, and on it the shout will be made. Thus, send blessings upon me often, for your blessings are presented to me.
