Ash-Shura · 42:21

21. Or do these idolaters have gods besides Allah, who have ordained for them religious matters that Allah did not authorize them to ordain such as ascribing partners to Allah, declaring unlawful what He made lawful and declaring lawful what He made unlawful? Had it not been for the fixed time that Allah had set to decide between those who differ, and that He will postpone them until such time, He would have decided between them. Those who wrong themselves by ascribing partners to Allah and committing sins, will have a painful punishment that awaits them on the day of resurrection.
