What is the ruling on the prayers I performed during the period of spotting, believing it to be urinary incontinence, and do they need to be made up? Is it permissible to read the Quran and perform the regular Sunnah prayers before the spotting ends?

There is a difference of opinion regarding the obligation to repeat prayers performed while in a state of continuous impurity due to ignorance, with the majority view being that it is obligatory to do so. It is not permissible to pray (whether obligatory or supererogatory) while in a state of continuous impurity; rather, one must wait until the the discharge of urine stops. As for reciting the Quran, there is no harm in doing so while there is impurity on the body.
