Verses including the word Authority

The people of the Book ask thee to cause a book to descend to them from heaven: Indeed they asked Moses for an even greater (miracle), for they said: "Show us Allah in public," but they were dazed for their presumption, with thunder and lightning.Yet they worshipped the calf even after clear signs had come to them; even so we forgave them; and gave Moses manifest proofs of authority. (Surah An-Nisa’, 153)

Say: the things that my Lord hath indeed forbidden are: shameful deeds, whether open or secret; sins and trespasses against truth or reason; assigning of partners to Allah, for which He hath given no authority; and saying things about Allah of which ye have no knowledge. (Surah Al-A‘raf, 33)

Or have We sent down authority to them, which points out to them the things to which they pay part-worship? (Surah Ar-Rum, 35)
