Sayyiduna Abu Hurairah (may Allah be pleased with him) reports that the Messenger of Allah (peace and blessings be upon him) said: "Whoever misses a fast of Ramadan without an allowance granted by Allah, then making up for that fast cannot be done even if he fasts for his entire life." In the narration of Muhammad bin Ja'far, there is this addition: "Even if he fasts (for his entire life), the compensation will not be fulfilled."

The Imam has narrated another chain of the aforementioned hadith, in which it is mentioned that the narrator says: I met Abu Mutawassit, and he narrated this hadith to me.

Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates from the Noble Prophet (peace and blessings be upon him) that he (peace and blessings be upon him) said: "When any one of you forgets while he is fasting and eats or drinks something, then he should complete his fast, for it is Allah Almighty who has fed him and given him drink."

It is narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, said: "Whoever breaks his fast in Ramadan out of forgetfulness, then neither making up the fast nor expiation is obligatory upon him." This is the narration of Muhammad. In the narration of Ibrahim, these words are mentioned: "Whoever eats or drinks out of forgetfulness in Ramadan, then there is neither making up the fast nor expiation upon him."

Lady Asma (may Allah be pleased with her) narrates that during the blessed era of the Messenger of Allah (peace and blessings be upon him), on a cloudy day in Ramadan, we broke our fast, and then the sun appeared. In the narration of Muhammad bin Alaa, it is mentioned: I said to Hisham. And in the narration of Abu Ammar, it is mentioned: Hisham was asked, were the Companions ordered to make up (qada) the fast? He replied: There is no alternative to this. Imam Abu Bakr (may Allah have mercy on him) says that in this narration, it is not mentioned that the Companions were ordered to make up the fast. Rather, it is the statement of Hisham (may Allah have mercy on him) that there is no alternative to this. These are not the words of the narration. In my view, qada is not obligatory upon them at that time when they broke the fast thinking the sun had set, and later it became known that the sun had not yet set. As is the statement of Sayyiduna Umar bin Khattab (may Allah be pleased with him): By Allah, as long as we avoid committing sin, we will not make up (qada). (That is, since we did not do it deliberately, we will not make up the fast.)
