The Book of the Prohibited actions
Abomination of Selecting Friday for Fasting
وَعَنْ مُحَمَّدِ بْنِ عَبَّادٍ قَالَ: سَأَلْتُ جَابِرًا رَضِيَ اللَّه عَنْهُ: أَنَهَى النَّبِيُّ صَلَّى اللَّه عَلَيْهِ وَسَلَّمَ عَنْ صَوْمِ يَوْمِ الْجُمُعَةِ؟ قَالَ: نَعَمْ ((مُتَّفَقٌ عَلَيْهِ)).
Muhammad bin 'Abbad (May Allah be pleased with him) said: I asked Jabir (May Allah be pleased with him). Did the Prophet (ﷺ) prohibit fasting on Friday?" He said, "Yes." [Al-Bukhari and Muslim].
