How to reconcile the hadith prohibiting fasting on Saturday with the hadith of Juwayriyyah: “Do you wish to fast tomorrow?”

The questioner : The hadith in which the Prophet (peace and blessings be upon him) entered upon one of his wives and found her fasting on Friday, and then he said to her, meaning: . This hadith, O Shaykh, has confused me in relation to the hadith: . What is your guidance, O Shaykh?

The Shaykh : There is no difficulty in this or in similar cases. This is because one of the known principles in reconciling hadiths is that when a prohibitive text and a permissive text conflict, the prohibitive text takes precedence over the permissive one. The hadith you mentioned is the hadith of Juwayriyyah (may Allah be pleased with her). The Messenger (peace and blessings be upon him) permitted her to fast if she fasted on Friday, either by fasting a day before it or a day after it, which is Thursday. This indicates permissibility. His statement (peace and blessings be upon him): indicates prohibition and restriction. Here, the aforementioned principle is applied: “When a prohibitive text and a permissive text conflict, the prohibitive text takes precedence over the permissive one.” Therefore, whoever wants to fast on Friday must fast on Thursday; otherwise, he should not fast on Friday and Saturday. This is because the hadith prohibiting fasting on Saturday lifts the permissibility that came in the hadith of Juwayriyyah. This is a path that a scholar must follow to resolve a type of conflict that may occur for the one who fasts. For example, we know that fasting on Thursday is desirable, just as fasting on Monday is. If it happens that the Day of 'Id al-Fitr falls on a Monday or a Thursday, or if one of the days of 'Id al-Adha falls on a Monday or a Thursday, is it fasted? The answer will certainly be no. In that case, what is the reconciliation between what was previously established regarding the legitimacy of fasting on Monday and Thursday, and the fact that in this specific instance, the ruling for Monday and Thursday has changed? It becomes something that is not permissible. This is the principle: “When a prohibitive text and a permissive text conflict, the prohibitive text takes precedence over the permissive one.” Fasting on Monday has virtue and its fasting is permissible, but fasting on the day of 'Id is prohibited, so the prohibition takes precedence over the permissibility. And so it is.
Yes.
