Salam Alaikum, I am muslim and trans, and you know in countries like Iran trans people can transition, because it is considered to be fine, the Quran doesn't say anything about trans people, and we change Allah's creation every day, by turning wheat into bread. Your faith is only between you and Allah, and you should disregard people saying that you can not be muslim and trans at the same time, they have no knowledge of that, and it would be like trying to play God's role for them, which is a sin.
