حَدَّثَنَا عَمْرٌو النَّاقِدُ ، حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ ، عَنْ عَبْدِ الْحَمِيدِ بْنِ جُبَيْرٍ ، عَنْ مُحَمَّدِ بْنِ عَبَّادِ بْنِ جَعْفَرٍ ، سَأَلْتُ جَابِرَ بْنَ عَبْدِ اللَّهِ رَضِيَ اللَّهُ عَنْهُمَا ، وَهُوَ يَطُوفُ بِالْبَيْتِ أَنَهَى رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عَنْ صِيَامِ يَوْمِ الْجُمُعَةِ ؟ ، فَقَالَ : " نَعَمْ وَرَبِّ هَذَا الْبَيْتِ " ،
Muhammad bin 'Abad. Ja'far reported: I asked Jabir bin 'Abdullah (Allah be pleased with both of them) as he was circumambulating the House (Ka’bah) whether the Messenger of Allah (ﷺ) had forbidden the fasting on Friday, whereupon he said: Yes, by the Lord of this House.
