The variants you're referring to are just changes in pronounciation not meaning. (It's called a qiraat and there are 10) It's like if someone from the UK and someone from San diego pronounce the same sentence. It will sound different because of their accent but it's the same thing. So I stand by what I say the quran is perfectly preserved. If you want to dive in further here is a video that address the issue of what you linked : https://youtu.be/eTz96M1AkVo?t=400 https://youtu.be/eTz96M1AkVo?t=400 There are many such online. At the end of the day there is only one Quran with 114 chapters it's start with surat Al-Fatiha and ends with the last surat An-Nas. If you want to learn more about Islam. I recommend the One Message Foundation channel : https://www.youtube.com/c/OneMessageFoundation/videos https://www.youtube.com/c/OneMessageFoundation/videos Finally, I want to invite you to become a muslim. Meaning, I invite you to submit your will to the one and only creator the same one who sent Moses, Jesus and Mohammed (Peace be upon them all) so that you may attain eternal paradise and avoid hell. In the end you make your choice and I'm only here as a conveyor of the message.
