I asked Jabir b. 'Abdullah (Allah be pleased with both of them) as he was circumambulating the House (Ka'ba) whether the Messenger of Allah ﷺ had forbidden the fasting on Friday, whereupon he said: Yes, by the Lord of this House.  

عَنْ مُحَمَّدِ بْنِ عَبَّادِ بْنِ جَعْفَرٍ سَأَلْتُ جَابِرَ بْنَ عَبْدِ اللَّهِ ؓ وَهُوَ يَطُوفُ بِالْبَيْتِ أَنَهَى رَسُولُ اللَّهِ ﷺ عَنْ صِيَامِ يَوْمِ الْجُمُعَةِ فَقَالَ نَعَمْ وَرَبِّ هَذَا الْبَيْتِ  

Muhammad b. 'Abbas b. Ja'far reported that he asked Jabir b. Abdullah (Allah be pleased with them), whether he had heard like this from the Messenger of Allah ﷺ.  

عَنِ النَّبِيِّ ﷺ  

None among you should observe fast on Friday, but only that he observes fast before it and after it.  

قَالَ رَسُولُ اللَّهِ ﷺ لاَ يَصُمْ أَحَدُكُمْ يَوْمَ الْجُمُعَةِ إِلاَّ أَنْ يَصُومَ قَبْلَهُ أَوْ يَصُومَ بَعْدَهُ  

Do not single out the night (preceding) Friday among the nights for prayer and do not single out Friday among days for fasting but only when anyone among you is accustomed to fast (on dates) which coincide with this day (Friday).  

عَنِ النَّبِيِّ ﷺ قَالَ لاَ تَخْتَصُّوا لَيْلَةَ الْجُمُعَةِ بِقِيَامٍ مِنْ بَيْنِ اللَّيَالِي وَلاَ تَخُصُّوا يَوْمَ الْجُمُعَةِ بِصِيَامٍ مِنْ بَيْنِ الأَيَّامِ إِلاَّ أَنْ يَكُونَ فِي صَوْمٍ يَصُومُهُ أَحَدُكُمْ
