Becoming pubescent and not making up for fast due to ignorance of its obligation

Q: I started my monthly period when I was 12 years old and did not know at the time that I had to make up for the number of fasting days on which I had my monthly period. But even on the days on which I did not have my monthly period, I did not fast, since I did not know that fasting was obligatory on me. What is your advice for me? I want to rest my conscience as I always feel that I neglected a duty.

A: You must make Tawbah (repentance to Allah) and make up for the missed days of fasting since you started your monthly period, which is a sign of puberty. Moreover, you must feed a Miskin (a needy person) with half a Sa` (1 Sa`=3 kg. Approx.) for each delayed missed day of fasting. (Part No. 9; Page No. 282) May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
