verily allah forgives not that partners should be set up with him in worship but he forgives except that to whom he pleases and whoever sets up partners with allah in worship he has indeed invented a tremendous sin.
إن الله لا يغفر أن يشرك به ويغفر ما دون ذلك لمن يشاء ومن يشرك بالله فقد افترى إثما عظيما
