We call their faith islam because it is the prophet who gave thm their islamic rights. even the mnere reality of his receiving revelation from allah about he munaiqeen and who they are still did not overide the fact that the prophet remained in obedience to the islamic dictates. The islamic dictates baased on this issue is that he narrated

"Whatever is establishd by certainty can only be removed by certainty"

so they were treated as muslims and had the same shariah rights as muslims, and that would not have been negated until a certainty was established i.e. their apostating. But since they did not explicitly apostate, they just hid their kufr, and the islamic shariah, ISLAM itself dos not necessitate that you act off of uncertainty, it only necessitate that you act on certainty.

so while we know that they had no islam and they were fake, they were still treated with the same islamic rights that every other muslim enjoys and is forced to adhere to.


so again, if islam does purify in and of itself on the mere islmic level, then explain whow there were such thing as munafiqeen. had islam purifed thehearts, there would not have been such thing called munaifqeen because by default everyone who coms to islam by defualt has their hearts purified.

again if what you say is true then why is the majority of muslims sinful. If what you say is true, then by the mere notion that they are muslims is by default assuming that their hwearts are purifed by default of their being muslim. but no person on earth, both muslims and non muslims views that by entering islam, then by default your heart is purified
