God does not forgive to have partners set up with Him, but He forgives other than that for whom He pleases. Whoever sets up partners with God has indeed strayed a far straying.
Translation endnotes
[4:116] Many of those who associate partners with God in his powers, such as His creative, legislative, guiding, or judiciary powers, do not accept that they are indeed polytheists who associate partners with God (6:22-23). See 4:48; 4:153.
