Muhammad ibn Yaqub narrated from Ali ibn Ibrahim, from Muhammad ibn Isa, from Ubayd, from Yunus, from Abu Basir and Samaah, from Abu Abdillah عليه السلام, peace be upon him: (Imam عليه السلام was asked) concerning ‘a people who fasted the month of Ramadan, then a black cloud covered them at the setting of the sun, so they thought that it was night.’ Imam عليه السلام said: “Upon the one who broke the fast is the fasting of that day (qada). Indeed Allah سبحانه وتعالى, Mighty and Majestic, says: ‘Then complete the fast until the night.’ (Surah Al-Baqarah 2:187) So whoever eats before the night enters, then making it up is upon him, because he ate deliberately.”
