Surah Al-Kahf (The Cave), Verse 15

هٰۤؤُلَآءِ قَوْمُنَا اتَّخَذُوْا مِنْ دُوْنِهٖۤ اٰلِهَةً لَوْلَا یَاْتُوْنَ عَلَیْهِمْ بِسُلْطٰنٍ بَیِّنٍ فَمَنْ اَظْلَمُ مِمَّنِ افْتَرٰی عَلَی اللّٰهِ كَذِبًا ۟

Haaa'ulaaa'i qawmunat takhazoo min dooniheee aalihatal law laa yaatoona 'alaihim bisultaanim baiyin; faman azlamu mimmaniftaraa 'alal laahi kazibaa

“"These our people have taken for worship gods other than Him: why do they not bring forward an authority clear (and convincing) for what they do? Who doth more wrong than such as invent a falsehood against Allah?”

Quran 18:15 (Yusuf Ali Translation)
