When is enough enough?

[u/KhajiitHasCares]

As-salamu alaykum all. I am wondering what the Islamic consensus would be on the state/fate of an individual who affirmed the following: ٱللَّهُ لَآ إِلَـٰهَ إِلَّا?

Or someone who affirmed the truthfulness of Al-Ikhlas?

Or someone who made the first shahada: أَشْهَدُ أَنْ لَا إِلَٰهَ إِلَّا ٱللَّٰهُ?

Is accepting Tahweed sufficient for salvation?
