However...

However, in the event that the delay is to the extent that in that time, the woman can perform two or more prayers – for example, she can perform maghrib and ʿishāʾ prayers before blood reaches the bottom of it again – then for those prayers [i.e. maghrib and ʿishāʾ], it is not necessary for her to perform another ghusl. In each case, for excessive istiḥāḍah, ghusl suffices in place of wuḍūʾ.
