Is continuity required for the three-day fast as expiation for an oath, and is it required to form the intention the night before for these fasts, or not?

The Shaykh : The second question: Regarding the three-day fast as expiation for an oath, is it required that the fasting be consecutive, and is it required to form the intention the night before, or not?
The answer: Regarding the first question, continuity is not required. The text is absolute: "three days." However, we always remind people on such occasions of the principle established by our Lord, Mighty and Majestic, in His saying: to the end of the verse. In it is an exhortation to hasten in good deeds, especially if they are obligatory. For this reason, the stronger opinion among scholars—and we are on the threshold of Hajj to the House of Allah the Exalted—is that Hajj is obligatory immediately for whoever is able to perform it, not to be delayed. This verse is the evidence for the stronger opinion, and clearer in its indication is the saying of the Prophet (peace and blessings be upon him): Based on this principle, one should hasten in performing acts of obedience, especially, as we mentioned earlier, those that are obligatory, such as the expiation for an oath. As for the second condition asked about, which is whether it is obligatory to form the intention the night before? The answer is affirmative. The rule in this matter is that for obligatory fasting, it is necessary to form the intention the night before, unlike voluntary fasting, where it is permissible to form the intention from the middle of the day. This is what is established from the Messenger (peace and blessings be upon him). Based on this, whoever has to fast three days as expiation for an oath, or any of the known expiations that involve fasting, must form the intention the night before.
