You’re getting things complicated without any reason. Kullu nafsin zaikatul mawt indeed means every soul shall taste death. Every soul means every soul.. theres no exception in arabic language as such. See the following verses :
2:282 : And fear the day when you shall be made to return to Allah; then shall *every soul *be paid in full what it has earned; and they shall not be wronged.
13:34 : Will then He, Who stands over every soul to note what it earns , let them go unpunished ?
Just to put an exception of Jesus still being alive and having nothing to say in regards to the verse from surah yasin is very naive. Wheres the exception? . If there are exceptions, as u said above, then the verses i provided above in response to ‘kullu nafsin zaikatul mawt’ should also have exceptions.
***If We grant long life to any, We cause him to be reversed in nature: Will they not then understand?
*either i’m missing something there, or you’re not getting what im saying.
