The Qur'an is written is Arabic. Because of this, it has been translated many times into many different languages. But, it is impossible to get a direct translation of Arabic into English, so there is variance in English Qur'an's. The variation between the translations is usually quite small, usually a couple of words or like different synonyms are used for certain words. Because the translated Qur'an's have been changed from their original form, many Muslims consider translated Qur'an's as not true forms of the Qur'an and do not have the deep meanings and intricacies of the original Qur'an. I attached a picture of two different Qur'an's next to each other.
