How can one make up missed prayers and fasting, taking into account the correct chronological and numerical order, and identifying the days that require feeding a needy person?

You are obligated to repent from forbidden acts and negligence in duties. You must immediately and systematically make up for the missed prayers that you believe are sufficient to absolve your responsibility, as much as you are able, without harming your livelihood. Regarding fasting, masturbation invalidates it if it leads to ejaculation. You must make up for the days whose fasts were invalidated by this, along with an expiation of feeding one poor person for each day you delayed making it up without excuse until another Ramadan began.
