The Holy Quran, Chapter Al-Ahqaf - الأحقاف

أَمْ يَقُولُونَ افْتَرَاهُ قُلْ إِنِ افْتَرَيْتُهُ فَلَا تَمْلِكُونَ لِي مِنَ اللَّهِ شَيْئاً هُوَ أَعْلَمُ بِمَا تُفِيضُونَ فِيهِ كَفَى بِهِ شَهِيداً بَيْنِي وَبَيْنَكُمْ وَهُوَ الْغَفُورُ الرَّحِيمُ

Or say they: He hath invented it? Say (O Muhammad): If I have invented it, still ye have no power to support me against Allah. He is best aware of what ye say among yourselves concerning it. He sufficeth for a witness between me and you And He is the Forgiving, the Merciful.

وَإِذَا حُشِرَ النَّاسُ كَانُوا لَهُمْ أَعْدَاء وَكَانُوا بِعِبَادَتِهِمْ كَافِرِينَ

And when mankind are gathered (to the Judgment) will become enemies for them, and will become deniers of having been worshipped.

قُلْ أَرَأَيْتُم مَّا تَدْعُونَ مِن دُونِ اللَّهِ أَرُونِي مَاذَا خَلَقُوا مِنَ الْأَرْضِ أَمْ لَهُمْ شِرْكٌ فِي السَّمَاوَاتِ اِئْتُونِي بِكِتَابٍ مِّن قَبْلِ هَذَا أَوْ أَثَارَةٍ مِّنْ عِلْمٍ إِن كُنتُمْ صَادِقِينَ

Say (unto them, O Muhammad): Have ye thought on all that ye invoke beside Allah? Show me what they have created of the earth. Or have they any Portion the heavens? Bring me a Scripture before this (Scripture), or some vestige of knowledge (in support of what ye say), if ye are truthful.

تَنْزِيلُ الْكِتَابِ مِنَ اللَّهِ الْعَزِيزِ الْحَكِيمِ

The revelation of the Scripture from Allah the Mighty, the Wise.
