Is it permissible to adopt the most lenient of fatwas regarding not redoing prayers that were performed without changing the sanitary pad, knowing that such a fatwa has been issued allowing it?

There are disagreements among scholars regarding whether a woman experiencing istihadah (non-menstrual vaginal bleeding) is obliged to re-tie her sanitary pad for every prayer. The more preponderant opinion is that it is not obligatory. The questioner must follow the opinion of a scholar whom she trusts. There is no harm for her in adopting the easier of the opinions when the religious jurists are equal in her view.
