What is required of one who broke his fast for several days in Ramadan during puberty (12-15 years old) due to bad company, and does not know their number? And is it better to perform the pre-prayer supererogatory acts (Sunan al-Rawatib) at home, despite the resulting delay in joining the Takbeerat al-Ihram or missing some rak'ahs with the Imam, based on the Prophet’s (peace be upon him) saying: "Pray, O people, in your homes, for the best of prayer is a person's prayer in his home, except for the obligatory prayer"?

What you have broken of the fast after puberty must be made up. If you do not know the number, then make up what you believe will absolve you. As for what you have broken of the fast before puberty, you are not obligated to make it up. Puberty is reached by the emission of semen, or the growth of pubic hair, or completing fifteen years of age. As for the regular supererogatory prayers (rawātib) at home, they are better. However, if you often miss some rak'ahs in the mosque, then praying them in the mosque is better, because the virtues of the obligatory prayers take precedence over the virtues of the supererogatory prayers. The virtue of the first row is connected to the prayer itself, so it takes precedence over the virtue of praying supererogatory prayers at home.
