Making AI images of human beings or maybe making different avatars is permissible or not? I have seen videos of scholars where they say drawing is not permissible but I am very confused with AI images as I am currently earning money through making AI portraits (By their permission and making Youtube thumbnails that requires different avatars to be included ( the videos are halal ) and my thumbnail concepts are halal too.
