The ruling on the condition of intention in voluntary fasting

Question:
The questioner says: Honorable Shaykh, may Allah grant you success, is intention a condition for voluntary fasting? And the second question: Is forbidding those who harm people to be done by the rulers, or is it a general duty?

Answer:
Yes, fasting requires intention. Every act of worship requires intention and is not valid without it, based on the saying of the Messenger (peace and blessings be upon him) However, the intention is not required to be made during the night. If a person reaches the morning without having intended to fast from the night, and he has not eaten or drunk, then he intends to fast during the day, there is no harm. There is no harm in intending to fast during the day, provided that he has not eaten or drunk after the dawn. This applies to voluntary fasting. As for obligatory fasting, the intention must be made from the beginning of the day, from the rise of the dawn. The difference between voluntary fasting and obligatory fasting is that in obligatory fasting, it is not permissible for the intention to be delayed beyond the rise of the dawn. As for voluntary fasting, the intention may be delayed beyond the rise of the dawn, provided that he does not eat or drink after the rise of the dawn. Yes.
