What is the ruling on the yellowish discharge that appeared after more than a day and a half of dryness, especially if its appearance coincided with the days of a previous menstrual cycle, knowing that the priority of the white discharge appearing is not certain? And is it obligatory to make up for prayers delayed due to an incorrect state of purity, and how should this make-up be performed?

The relied-upon opinion for us is that yellowish and brownish discharges are considered menstruation during the period of the custom, and likewise if they are connected to blood. Ghusl (ritual bath) becomes obligatory immediately upon seeing purity. What the questioner saw of yellowish discharge on the eighth day of her custom is considered menstruation. There is another opinion permitting waiting for a day and a half for those who perceive purity by dryness. There is a difference of opinion regarding the obligation to re-perform the prayers that the questioner offered while not in a state of purity.
