refutation of accusations against the Prophet

قُل لَّآ أَقُولُ لَكُمْ عِندِى خَزَآئِنُ ٱللَّهِ وَلَآ أَعْلَمُ ٱلْغَيْبَ وَلَآ أَقُولُ لَكُمْ إِنِّى مَلَكٌ ۖ إِنْ أَتَّبِعُ إِلَّا مَا يُوحَىٰٓ إِلَىَّ ۚ قُلْ هَلْ يَسْتَوِى ٱلْأَعْمَىٰ وَٱلْبَصِيرُ ۚ أَفَلَا تَتَفَكَّرُونَ

Say, [O Muḥammad], "I do not tell you that I have the depositories [containing the provision] of Allāh or that I know the unseen, nor do I tell you that I am an angel. I only follow what is revealed to me." Say, "Is the blind equivalent to the seeing? Then will you not give thought?"

أَمْ يَقُولُونَ ٱفْتَرَىٰهُ ۖ قُلْ فَأْتُوا۟ بِسُورَةٍ مِّثْلِهِۦ وَٱدْعُوا۟ مَنِ ٱسْتَطَعْتُم مِّن دُونِ ٱللَّهِ إِن كُنتُمْ صَـٰدِقِينَ

Or do they say [about the Prophet (ﷺ)], "He invented it?" Say, "Then bring forth a sūrah like it and call upon [for assistance] whomever you can besides Allāh, if you should be truthful."

۞ قُلْ إِنَّمَآ أَعِظُكُم بِوَٰحِدَةٍ ۖ أَن تَقُومُوا۟ لِلَّهِ مَثْنَىٰ وَفُرَٰدَىٰ ثُمَّ تَتَفَكَّرُوا۟ ۚ مَا بِصَاحِبِكُم مِّن جِنَّةٍ ۚ إِنْ هُوَ إِلَّا نَذِيرٌ لَّكُم بَيْنَ يَدَىْ عَذَابٍ شَدِيدٍ

Say, "I only advise you of one [thing] - that you stand for Allāh, [seeking truth] in pairs and individually, and then give thought." There is not in your companion any madness. He is only a warner to you before a severe punishment.

أَمْ عِندَهُمُ ٱلْغَيْبُ فَهُمْ يَكْتُبُونَ

Or have they [knowledge of] the unseen, so they write [it] down?
