“The Messenger of Allah ﷺ forbade fasting on a Friday unless it (is joined to) the day before or the day after.”  

نَهَى رَسُولُ اللَّهِ ﷺ عَنْ صَوْمِ يَوْمِ الْجُمُعَةِ إِلاَّ بِيَوْمٍ قَبْلَهُ أَوْ يَوْمٍ بَعْدَهُ  

“While I was circumambulating the House, I asked Jabir bin ‘Abdullah: ‘Did the Prophet ﷺ forbid fasting on a Friday?’ He said: ‘Yes, by the Lord of this House.’”  

سَأَلْتُ جَابِرَ بْنَ عَبْدِ اللَّهِ وَأَنَا أَطُوفُ بِالْبَيْتِ أَنَهَى النَّبِيُّ ﷺ عَنْ صِيَامِ يَوْمِ الْجُمُعَةِ؟ قَالَ نَعَمْ وَرَبِّ هَذَا الْبَيْتِ  

“I rarely saw the Messenger of Allah ﷺ not fasting on a Friday.”  

قَلَّمَا رَأَيْتُ رَسُولَ اللَّهِ ﷺ يُفْطِرُ يَوْمَ الْجُمُعَةِ
