Is the purity considered valid and the ghusl permissible after seeing dryness following the cleaning of the area with water, with a slight yellowish discharge occurring after the ghusl and no return of blood or brownish discharge, and is it obligatory to repeat the prayers of the two days after this ghusl?

The relied-upon opinion is that yellowish and brownish discharges are considered menstruation if a woman sees them during her regular period or if they are connected to blood. If a woman sees yellowish discharge after performing ghusl during her regular period, she must perform ghusl again after seeing purity, and she must repeat the prayers of the two days in which she did not perform ghusl. Ghusl for janabah suffices for ghusl for menstruation.
