FIRST OF ALL I DID NOT KNEW THAT MASTURBATION BREAKS FASTS.I MASTURBATED DURING RAMZAN FASTS AND THEN I CAME TO KNOW THAT IT BREAKS RAMZAN FASTS.AFTER KNOWING THAT,I THOUGHT MY FASTS IS ALREADY BROKEN DUE TO MASTURBATION .I DRANK WATER DURING THAT FAST. NOW DO I HAVE TO KEEP ONLY QADA ROZA OR GIVE KAFFARAH ALSO.
Only the qaza of that fast is wajib not kaffarah. Note that masturbation is haram; hence, it is necessary to do tauba and istighfar.
Allah (Subhana Wa Ta’ala) knows Best
