How do I make up for the fasting days that I broke by masturbating during the daytime in Ramadan, without knowing that this nullifies the fast? Is fidyah obligatory upon me, knowing that I am a student and do not possess money? Is it sufficient to pay one and a half kilograms of flour or rice? What are the consequences if I die before completing the qadaa' (making up of missed fasts)?

You must make up for the days of fasting that were invalidated due to masturbation, because your knowledge of its prohibition is sufficient to invalidate the fast, even if you were ignorant of it being a fast-breaker. You must make up for it immediately without delay, unless there is a valid excuse. You must also feed one poor person for each day you delayed making up for it. The feeding is estimated at half a sa' of rice (approximately one and a half kilograms). The expiation remains your responsibility until you are able to perform it. If death overtakes you while you are making up for the fast, there is nothing upon you, and your heirs must feed on your behalf for each remaining day, or they may fast on your behalf.
