Machine translationRead the Arabic original
Question:
The Shaykh (may Allah have mercy on him) said: A man swore, saying, “By Allah, I will pray the sunnah of one rak'ah daily,” but then he did not pray the Fajr prayer for several days. Is he subject to being declared a disbeliever for the number of days?
Answer:
Yes, if he said "daily," that means every day, so he owes expiations for the number of days he missed. Yes.
