What is the ruling on making up prayers and fasting missed due to ignorance that brown discharge after menstruation is considered menses, and that ghusl is obligatory after masturbation? Are the past days in which fasting was observed with these actions considered deliberate breaking of the fast? And is the method of making up prayers by dedicating three missed prayers after each obligatory prayer correct?

Vaginal discharge (Al-Kudrah) after seeing purity (Al-Tuhr) outside the usual period is not considered menstruation. However, if the discharge is connected to blood, it is considered menstruation by the Hanbalis and the majority of scholars. In this case, prayers offered after purity from menstruation, but without performing ghusl after this discharge, must be made up.

Regarding masturbation: It does not necessitate ghusl unless it is accompanied by the emission of semen. If semen was emitted and you did not perform ghusl, there is a difference of opinion regarding the necessity of making up the prayers.

As for fasting: You are not required to make up the fasts due to your ignorance that this was among the things that invalidate fasting.
