B.) And the ruling for the ones who are excused is such that for every prayer, for instance, for the time of zuhar prayer one should make the ablution and with that ablution one can pray the farz, Sunnah, nafal, and can even make up any of the missed prayers. The continuation of the flow of that substance would not be the cause to break the ablution. When the time of zuhar expires then the ablution would expire as well. Subsequently, for the ASR prayer the person would have to make a new ablution. It’s not necessary for the ones who are excused to have the excusable reason during the entire time of a prayer as long as it appears at least one or two times during that time of the prayer, the person would still be considered excused. When the person has one complete time of a prayer in such a manner that the plea or the excusable reason doesn’t appear even once then the person is no longer excused.
