Al-Kāfi - The Book of Fasting

Chapter: The Day That Is Doubtful About Its Being of the Month of Sha‘ban or the Month of Ramadan َّدُ بْنُ يَحْيَى عَنْ ٠َّدِ بْنِ الْحُسَيْنِ عَنْ عُبَيْسِ بْنِ هِشَا٠ٍ عَنِ الْخَضِرِ بْنِ عَبْدِ الْ٠ٍ قَالَ سَأَلْتُ أَبَا الْحَسَنِ (عَلَيْهِ السَّلاَ٠ِ الَّذِي يُشَكُّ فِيهِ فَإِنَّ النَّاسَ يَزْعُ٠َنْ أَفْطَرَ يَوْ٠َضَانَ فَقَالَ كَذَبُوا إِنْ كَانَ ٠َضَانَ فَهُوَ يَوْ٠ٌ وُفِّقَ لَهُ وَإِنْ كَانَ ٠ِنْ غَيْرِهِ فَهُوَ بِ٠8.

Muhammad ibn Yahya has narrated from Muhammad ibn al-Husayn from ‘Ubays ibn Hisham from al-Hadramiy ibn ‘Abd al-Malik from Muhammad ibn Hakim who has said the following: “I once asked abu al-Hassan (a.s.), about the case of a day about which people have doubts. People think if one fasts on such a day, it is like destroying one day of fasting in the month of Ramadan. He (the Imam) said, ‘They have spoken a lie.

If it is of the month of Ramadan, it is a fortunate chance for him; and if it is of other days then it is like any of the past days.’” جهول - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (6/240))
