Surah Al-A'raf (The Heights), Verse 37

فَمَنْ اَظْلَمُ مِمَّنِ افْتَرٰی عَلَی اللّٰهِ كَذِبًا اَوْ كَذَّبَ بِاٰیٰتِهٖ اُولٰٓىِٕكَ یَنَالُهُمْ نَصِیْبُهُمْ مِّنَ الْكِتٰبِ حَتّٰۤی اِذَا جَآءَتْهُمْ رُسُلُنَا یَتَوَفَّوْنَهُمْ قَالُوْۤا اَیْنَ مَا كُنْتُمْ تَدْعُوْنَ مِنْ دُوْنِ اللّٰهِ قَالُوْا ضَلُّوْا عَنَّا وَشَهِدُوْا عَلٰۤی اَنْفُسِهِمْ اَنَّهُمْ كَانُوْا كٰفِرِیْنَ ۟

“Who is more unjust than one who invents a lie against Allah or rejects His Signs? For such, their portion appointed must reach them from the Book (of decrees): until, when our messengers (of death) arrive and take their souls, they say: "Where are the things that ye used to invoke besides Allah?" They will reply, "They have left us in the lurch," And they will bear witness against themselves, that they had rejected Allah.”
