Fasting: A Child Breaking a Recommended Fast When Forbidden by Parents
Practical Laws of Islam as per the teachings of Ayatullah Sistani
Ruling 1710
If a child keeps a recommended fast without the consent of his father or mother and during the day his father or mother forbid him to continue keeping his fast, in the event that the child’s opposition may annoy the parent due to the parent’s compassion for his or her child, the child must break his fast.
