عَنْ مُحَمَّدِ بْنِ عَبَّادِ بْنِ جَعْفَرٍ أَنَّهُ سَأَلَ جَابِرَ بْنَ عَبْدِ اللَّهِ الْأَنْصَارِيَّ رَضِيَ اللَّهُ عَنْهُ وَهُوَ يَطُوفُ بِالْبَيْتِ: أَسْمِعْتَ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ يَنْهَى عَنْ صِيَامِ يَوْمِ الْجُمُعَةِ؟ قَالَ: نَعَمْ وَرَبِّ هَذَا الْبَيْتِ!
It is narrated from Muhammad bin Abbad that he asked Sayyiduna Jabir bin Abdullah Ansari, may Allah be pleased with him, while he was performing Tawaf of the House of Allah, "Did you hear the Noble Prophet, peace and blessings be upon him, forbidding fasting on Friday?" He said, "Yes, by the Lord of this House!"
