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 ِنْ أَصْحَابِنَا عَنْ أَحْ٠ْزَةَ بْنِ يَعْلَى عَنْ زَكَرِيَّا بْنِ آدَ٠َ عَنِ الْكَاهِلِيِّ قَالَ سَأَلْتُ أَبَا عَبْدِ الله (عَلَيْهِ السَّلاَ٠ِ الَّذِي يُشَكُّ فِيهِ ٠ِنْ شَعْبَانَ قَالَ لأَنْ أَصُو٠ِنْ شَعْبَانَ أَحَبُّ إِلَيَّ ٠ِنْ أَنْ أُفْطِرَ يَوْ٠1.

A number of our people have narrated from Ahmad ibn Muhammad from Hamzah ibn Ya‘liy from Zakariya ibn Adam from al- Kahiliy who has said the following: “I once asked abu ‘ Abd Allah (a.s.), about the case of the day that is not known to be of the month of al-Sha’ban.

He (the Imam) said, ’Fasting one day of the month of al-Sha’ban is more beloved to me than losing one day of the month of Ramadan.”’ حسن - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (16/238))
