disbelief and stubbornness

أَوَلَمْ يَتَفَكَّرُوا۟ ۗ مَا بِصَاحِبِهِم مِّن جِنَّةٍ ۚ إِنْ هُوَ إِلَّا نَذِيرٌ مُّبِينٌ

Then do they not give thought? There is in their companion [i.e., Muḥammad (ﷺ)] no madness. He is not but a clear warner.

وَيَقُولُ ٱلَّذِينَ كَفَرُوا۟ لَسْتَ مُرْسَلًا ۚ قُلْ كَفَىٰ بِٱللَّهِ شَهِيدًۢا بَيْنِى وَبَيْنَكُمْ وَمَنْ عِندَهُۥ عِلْمُ ٱلْكِتَـٰبِ

And those who have disbelieved say, "You are not a messenger." Say, [O Muḥammad], "Sufficient is Allāh as Witness between me and you, and [the witness of] whoever has knowledge of the Scripture."

أَوْ يُلْقَىٰٓ إِلَيْهِ كَنزٌ أَوْ تَكُونُ لَهُۥ جَنَّةٌ يَأْكُلُ مِنْهَا ۚ وَقَالَ ٱلظَّـٰلِمُونَ إِن تَتَّبِعُونَ إِلَّا رَجُلًا مَّسْحُورًا

Or [why is not] a treasure presented to him [from heaven], or does he [not] have a garden from which he eats?" And the wrongdoers say, "You follow not but a man affected by magic."

لَا يُؤْمِنُونَ بِهِۦ حَتَّىٰ يَرَوُا۟ ٱلْعَذَابَ ٱلْأَلِيمَ

They will not believe in it until they see the painful punishment.

فَهُمْ عَلَىٰٓ ءَاثَـٰرِهِمْ يُهْرَعُونَ

So they hastened [to follow] in their footsteps.

ثُمَّ تَوَلَّوْا۟ عَنْهُ وَقَالُوا۟ مُعَلَّمٌ مَّجْنُونٌ

Then they turned away from him and said, "[He was] taught [and is] a madman."

وَإِذَا تُتْلَىٰ عَلَيْهِمْ ءَايَـٰتُنَا بَيِّنَـٰتٍ قَالَ ٱلَّذِينَ كَفَرُوا۟ لِلْحَقِّ لَمَّا جَآءَهُمْ هَـٰذَا سِحْرٌ مُّبِينٌ

And when Our verses are recited to them as clear evidences, those who disbelieve say of the truth when it has come to them, "This is obvious magic."

فَقَالُوٓا۟ أَبَشَرًا مِّنَّا وَٰحِدًا نَّتَّبِعُهُۥٓ إِنَّآ إِذًا لَّفِى ضَلَـٰلٍ وَسُعُرٍ

And said, "Is it one human being among us that we should follow? Indeed, we would then be in error and madness.
