Al-A'raf - 7:37

فَمَنْ أَظْلَمُ مِمَّنِ افْتَرَى عَلَى اللّهِ كَذِبًا أَوْ كَذَّبَ بِآيَاتِهِ أُوْلَـئِكَ يَنَالُهُمْ نَصِيبُهُم مِّنَ الْكِتَابِ حَتَّى إِذَا جَاءتْهُمْ رُسُلُنَا يَتَوَفَّوْنَهُمْ قَالُواْ أَيْنَ مَا كُنتُمْ تَدْعُونَ مِن دُونِ اللّهِ قَالُواْ ضَلُّواْ عَنَّا وَشَهِدُواْ عَلَى أَنفُسِهِمْ أَنَّهُمْ كَانُواْ كَافِرِينَ
[7:37]
Who is then more unjust than he who forges a lie against Allah or rejects His communications? (As for) those, their portion of the Book shall reach them, until when Our messengers come to them causing them to die, they shall say: Where is that which you used to call upon besides Allah? They would say: They are gone away from us; and they shall bear witness against themselves that they were unbelievers
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.
Who doeth greater wrong than he who inventeth a lie concerning Allah or denieth Our tokens. (For such) their appointed portion of the Book (of destiny) reacheth them till, when Our messengers come to gather them, they say: Where (now) is that to which ye cried beside Allah? They say: They have departed from us. And they testify against themselves that they were disbelievers.
