Is consecutiveness required in the three-day fast for the expiation of an oath? And is it required to fix the intention for it the night before, or not?

The Shaykh : The second question: He said: Regarding the three-day fast for the expiation of an oath; is it required that the fasting be consecutive? And is it required to fix the intention the night before, or not?
The answer regarding the first condition is that consecutiveness is not required; the text is absolute regarding three days. However, we always remind people on such occasions of the principle our Lord (Mighty and Majestic) established in His saying (Glorified and Exalted is He): to the end of the verse; for it contains an exhortation to hasten in good deeds, especially if they are among the obligatory ones. For this reason, the stronger opinion among the scholars—and we are on the threshold of Hajj to the House of Allah the Exalted—was that the stronger opinion is that Hajj is obligatory immediately for whoever is able to find a way to it, not with delay. This verse is among the evidence for this stronger opinion, and more explicit in its indication is His saying (peace and blessings be upon him): . Based on this principle, one should hasten to perform acts of obedience, especially, as we said earlier, those that are obligatory, such as the expiation of an oath.
As for the second condition asked about, which is: Is it obligatory to fix the intention the night before? The answer is affirmative. The rule in this matter is—may Allah have mercy on you—the rule in this matter is that for obligatory fasting, it is necessary to fix the intention the night before, unlike voluntary fasting; for it is permissible to form the intention from the forenoon. This is what is established from the Messenger (peace and blessings be upon him). Based on this, whoever has a three-day fast for the expiation of an oath, or any expiation among the known expiations that involve fasting, must fix the intention the night before.
