Qur'an 7:37

فَمَنْ أَظْلَمُ مِمَّنِ ٱفْتَرَىٰ عَلَى ٱللَّهِ كَذِبًا أَوْ كَذَّبَ بِـَٔايَـٰتِهِۦٓ ۚ أُو۟لَـٰٓئِكَ يَنَالُهُمْ نَصِيبُهُم مِّنَ ٱلْكِتَـٰبِ ۖ حَتَّىٰٓ إِذَا جَآءَتْهُمْ رُسُلُنَا يَتَوَفَّوْنَهُمْ قَالُوٓا۟ أَيْنَ مَا كُنتُمْ تَدْعُونَ مِن دُونِ ٱللَّهِ ۖ قَالُوا۟ ضَلُّوا۟ عَنَّا وَشَهِدُوا۟ عَلَىٰٓ أَنفُسِهِمْ أَنَّهُمْ كَانُوا۟ كَـٰفِرِينَ

“And who is more unjust than one who invents about Allāh a lie or denies His verses? Those will attain their portion of the decree until, when Our messengers [i.e., angels] come to them to take them in death, they will say, "Where are those you used to invoke besides Allāh?" They will say, "They have departed from us," and will bear witness against themselves that they were disbelievers.”
