Initial letters

Some times ago I was studying one printed quran . in this quran had been changed dictation of some words. One of changes was in verse 19:30. the word Aataanee (ءاتيني ) was with Alef in this printed quran like (ءاتاني ). If this word be with Alef instead of Ya , many mathematical miracle regarding sura 19 would be destructed . GOD almighty has saved Quran with dictation 99.999999% , therefore we don't must change letters in it optionally.
