Al-Kāfi - The Book of Fasting

Chapter: The Case of One who Eats or Drinks out of Forgetfulness During the Month of Ramadan َّدُ بْنُ يَحْيَى عَنْ أَحْ٠َانَ بْنِ عِيسَى عَنْ سَ٠َاعَةَ قَالَ سَأَلْتُهُ عَنْ رَجُلٍ صَا٠َضَانَ فَأَكَلَ وَشَرِبَ نَاسِياً قَالَ يُتِ٠َهُ وَلَيْسَ عَلَيْهِ قَضَاؤُهُ. 2.

Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from ‘Uthman ibn ‘Isa from Sama‘ah, who has said the following: “I once asked him (the Imam) (a.s.), about a man who because of forgetfulness when fasting in the month of Ramadan eats and drinks. He (the Imam) said, ‘He is not required to complete its Qada’ (compensatory fast).”’ وثق - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (16/271))
