fastingimam-aliahl-al-bayt
وَ بِهَذَا الْإِسْنَادِ عَنِ الْحُسَیْنِ بْنِ سَعِیدٍ عَنْ حَمَّادِ بْنِ عِیسَی عَنْ حَرِیزٍ قَالَ: قِیلَ لِأَبِی عَبْدِ اللَّهِ ع مَا جَاءَ فِی صَوْمِ الْأَرْبِعَاءِ فَقَالَ قَالَ عَلِیٌّ ع إِنَّ اللَّهَ عَزَّ وَ جَلَّ خَلَقَ النَّارَ یَوْمَ الْأَرْبِعَاءِ فَأَحَبَّ صَوْمَهُ لِیُتَعَوَّذَ بِاللَّهِ مِنَ النَّارِ.
5. And from the previous chain from al-Hussain b. Sa’eed from Hamad b. Isa from Hareez who said: Imam Ja’far Sadiq (a.s.) was asked regarding fasting on Wednesday. He replied that Ali (a.s.) used to say, “The Almighty Allah created Hell on Wednesday. He likes the person fasting on this day seeking protection against the fire of Hell.”
