Is it permissible to make the intention for voluntary fasting after Fajr?

Question:
May Allah reward you. The honorable scholar says: If I forget to make the intention to fast, is it permissible for me, after I wake up from sleep following the Fajr prayer, to complete my fast, or not? If you have not eaten or drunk after Fajr, and the fast is

Answer:
voluntary, there is no harm in making the intention to fast during the day for a voluntary fast, on the condition that you have not eaten or drunk after Fajr. As for the obligatory fast, the fast of obligation, this is not valid with an intention made during the day, even if you have not eaten or drunk; it is not valid with an intention made during the day because you did not make the intention from the start of the day, and the intention must accompany the entire day. However, if you intend to fast an obligatory fast as a make-up, or a vow, or the fast of Ramadan, and you are determined to fast, but you are not certain due to shukr, it is obligatory for you to fast, and your fast is valid because you made the intention from the night. Eating and drinking at suhur is not a condition; this is not a condition. You made the intention from the night, the intention is present, so when you wake up, you continue with this intention and complete your day; your fast is valid if nothing contradicts it. Yes, the intention is present, and you have not eaten or drunk after Fajr, so the fast is valid. And the Prophet (peace and blessings be upon him) said: As for the voluntary fast, if you reach the morning without having made the intention to fast, and it did not occur to you that you would fast, but when you reach the morning you decide to fast, and you have not eaten or drunk after Fajr, it is permissible because the voluntary fast is broader than the obligatory fast, and because the Prophet (peace and blessings be upon him) entered his house and asked his family if they had anything? They said, no. He said, "Then I am fasting."
