But the question was not phrased like that response … In your question the person had already accepted Islam. Just like with kids we do not expect them to do everything … But clothing them is actually the most apparent and easiest ways to “feel” Muslim. Although the most vital aspect in the afterlife is for to die in Tawhid, the most effective way to ensure that is be protected in every way … I’m not saying that we expect them to be leading prayers and giving sermons on day 1 … But prayer has a premise … So we teach them wudu, first by imitation, we get them to recite Shahadah, by imitation, if they want to pray we show them the adab for it … I.e. wear clean clothes … For a starter …
My point was for a rookie Muslim there is a certain level of attire, sulook, and ritual expected, then each of these increase … We don’t isolate any one of these areas and focus on them.
