Details of interpreting verses from the Qur'an and obvious blunders

Re: Details of interpreting verses from the Qur’an and obvious blunders

How come that when the phrase “Qad Khalat” appears in other verses of the Quran in connection with a person it means “passed away” i.e. died, but here it means ascended to Heaven also? How come that when you look up the term “Khala” in an Arabic Lexicon, it means to pass away or die i.e. “Mawt”? How come in all translations, it’s translated as passed away or died? What did Hazrat Abu Bakr RA say after the Prophet’s (PBUH) death again?
