What is the ruling concerning the prayers I have performed since the age of eighteen, while experiencing discharge, and being unaware that it invalidates wudu'? And what is the ruling concerning the prayers I was unable to make up due to my ignorance of how to perform wudu' for them? Is it permissible for me to make up a missed prayer along with a current prayer with a single wudu'? What is the ruling concerning my fasting before reaching the age of eighteen without praying? And what is the ruling concerning my fasting while being unaware of the signs of purity from menstruation?

The prayers you performed without ablution due to the secretions: They are valid according to the Malikis, who do not necessitate ablution for perpetual ritual impurity, and there is no blame upon you for acting upon this.

Making up missed prayers: You are obligated to make them up to the best of your ability, in a way that does not harm you. The Malikis hold that it suffices to pray two days' worth of prayers with each day.

Continuous discharge (Sals al-Rutubat): You perform ablution after the entry of the prayer time and pray whatever obligatory and supererogatory prayers you wish until that time exits.

Fasting: Your fast is valid even if you neglected prayer, as purity is not a condition for its validity.

Yellow and brownish discharge (Safra and Kudra): If you fasted while these were present and they are considered menstruation, then you must make up those days.
