وَمَنْ أَظْلَمُ مِمَّنِ افْتَرَىٰ عَلَى اللَّهِ كَذِبًا أَوْ كَذَّبَ بِالْحَقِّ لَمَّا جَاءَهُ ۚ أَلَيْسَ فِي جَهَنَّمَ مَثْوًى لِّلْكَافِرِينَ (68)
(29:68) Who can be more unjust than he who foists a lie on Allah or gives the lie to the Truth after it has come to him? *106 Is Hell not the resort of the unbelievers?
*106) That is, "The Prophet has made a claim to Prophethood, and you have denied him. Now there can be only two alternatives: If the Prophet has made a false claim in the name of Allah, there can be no one more wicked than he, and if you have belied a true Prophet, there can be no one more wicked than you."
