[Machine] I asked Jabir ibn Abdullah, "Did the Messenger of Allah, ﷺ , prohibit fasting on Fridays?" He replied, "Yes, by the Lord of this house."  

قُلْتُ لِجَابِرِ بْنِ عَبْدِ اللهِ هَلْ نَهَى رَسُولُ اللهِ ﷺ عَنْ صَوْمِ يَوْمِ الْجُمُعَةِ؟ قَالَ أَيْ وَرَبِّ هَذَا الْبَيْتِ  

The Messenger of Allah ﷺ as saying: None of you must fast on Friday unless he fasts the day before or the day after. (Using translation from Abū Dāʾūd 2420)   

قَالَ رَسُولُ اللهِ ﷺ لَا يَصُومُ أَحَدُكُمْ يَوْمَ الْجُمُعَةِ إِلَّا أَنْ يَصُومَ قَبْلَهُ يَوْمًا أَوْ بَعْدَهُ يَوْمًا  

[Machine] Regarding Al-A'mash,  

عَنِ الْأَعْمَشِ  

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). (Using translation from Muslim 1144b)   

عَنِ النَّبِيِّ ﷺ قَالَ لَا تَخْتَصُّوا لَيْلَةَ الْجُمُعَةِ بِقِيَامٍ مِنْ بَيْنِ اللَّيَالِي وَلَا تَخْتَصُّوا يَوْمَ الْجُمُعَةِ بِصِيَامٍ مِنْ بَيْنِ الْأَيَّامِ إِلَّا أَنْ يَكُونَ فِي صَوْمٍ يَصُومُهُ أَحَدُكُمْ  

[Machine] "The Prophet ﷺ entered upon her on a Friday while she was fasting, and he asked her, 'Did you fast yesterday?' I said, 'No.' He said, 'Will you fast tomorrow?' I said, 'No.' He said, 'Then break your fast (today) and by its chain of narrators, he (Yahya) said, narrating from Shu'bah through a similar chain of narrators."  

أَنَّ النَّبِيَّ ﷺ دَخَلَ عَلَيْهَا يَوْمَ جُمُعَةٍ وَهِيَ صَائِمَةٌ فَقَالَ صُمْتِ أَمْسِ؟ فَقُلْتُ لَا قَالَ فَتَصُومِينَ غَدًا؟ قُلْتُ لَا قَالَ فَأَفْطِرِي 8492 وَبِإِسْنَادِهِ قَالَ ثنا يُوسُفُ ثنا مُسَدَّدٌ ثنا يَحْيَى عَنْ شُعْبَةَ بِإِسْنَادِهِ نَحْوَهُ
