The ruling on one who conditions fasting on a specific day upon his will and then forgets
Machine translationRead the Arabic original
Question:
If a man says: "I will fast on a day, if Allah wills," knowing that this day is Monday, and then he forgets to fast, what is required of him?
Answer:
He owes nothing; because this is not called a vow. This is a promise conditioned upon his will, so Allah did not will it for him. If he says: "If Allah wills, I will fast on Thursday," "If Allah wills, I will fast on Monday," "If Allah wills, I will visit so-and-so," "If Allah wills, I will perform Hajj," "If Allah wills, I will pray the Dhuha prayer," all of this requires nothing of him if he does not do it. Yes.
