Is it valid to combine the opinion that one should wait a full day to ensure purity during the accustomed menstrual period, and the opinion that one should perform ghusl upon seeing purity for one hour after the end of the accustomed menstrual period, knowing that purity is indicated by dryness and not by a white discharge, and that dryness is intermittent at the end of the accustomed period?

The interspersed purity during menstruation is considered ṭuhur (purity) by the Malikis and Hanbalis (the doctrine of talfiq/conjunction), where the ruling revolves around the presence of blood (the adha or harm). Meanwhile, the Hanafis and Shafi'is (the doctrine of sahb/drawing out) hold that the interspersed purity still retains the ruling of menstruation. Those who advocate for talfiq differed regarding the duration of purity to be considered. The prevalent view among the Malikis and Hanbalis is that it is ṭuhur no matter how short. However, some scholars among those who held this view believe that the purity should not be less than a day, unless the woman sees an indication of purity, such as the white discharge (al-qussah al-bayda') or if the cessation occurs at the end of her customary period.
