What is entailed for a daughter who broke her fast for two days in Ramadan when she was fifteen years old without a valid excuse, knowing that her age is now seventeen?

Deliberately breaking the fast during the day in Ramadan without a legitimate Shari excuse is a major sin that necessitates sincere repentance (tawbah nasuh). If the breaking of the fast was by eating, drinking, or similar acts, but not by sexual intercourse, then the person who broke the fast is only required to make up for the missed days (qada'), without expiation (kaffarah). However, if the breaking of the fast was by sexual intercourse, then expiation becomes obligatory. Deliberately delaying the making up of missed fasts necessitates a minor expiation (feeding one poor person for each day). However, if the delay was due to ignorance, forgetfulness, or an excuse such as pregnancy or breastfeeding, then only the making up of the fasts is required.
