You are not removing the apparent contradiction but you are merely using other verses to show they apparently contradict with that verse … the REASON why we say that the verse does not mean “every soul” because the grammar itself demands an exception to be understood. And of course we can be certain what the Qur’an says … I can be certain that “Not every soul shall taste death” - you response to “every created soul” is interpolation you have added the word “created” it is not present in the words … my explanation shows that the exception is inherent in the language …
Also, I can be certain that “every angel bowed to Adam (AS) except Iblis”
Also … I can be certain that there is NO deity except Allah … This is the highest form of emphasis - by negating the opposite possibility … When we say “La ilaha ilAllah” we are negating anything for worship except Allah (SWT) …
You see you think that the Qur’an tell us things in discrete ways … but it doesn’t unless the grammar is discrete … if it is not discrete we can be CERTAIN that the topic at hand is not absolute and is talking in general terms with some exceptions.
