refutation of disbeliever accusations

وَكَذَٰلِكَ نُصَرِّفُ ٱلْـَٔايَـٰتِ وَلِيَقُولُوا۟ دَرَسْتَ وَلِنُبَيِّنَهُۥ لِقَوْمٍ يَعْلَمُونَ

And thus do We diversify the verses so they [i.e., the disbelievers] will say, "You have studied," and so We may make it [i.e., the Qur’ān] clear for a people who know.

وَمَا كُنتَ تَتْلُوا۟ مِن قَبْلِهِۦ مِن كِتَـٰبٍ وَلَا تَخُطُّهُۥ بِيَمِينِكَ ۖ إِذًا لَّٱرْتَابَ ٱلْمُبْطِلُونَ

And you did not recite before it any scripture, nor did you inscribe one with your right hand. Then [i.e., otherwise] the falsifiers would have had [cause for] doubt.

أَمْ يَقُولُونَ شَاعِرٌ نَّتَرَبَّصُ بِهِۦ رَيْبَ ٱلْمَنُونِ

Or do they say [of you], "A poet for whom we await a misfortune of time"?

أَمْ تَسْـَٔلُهُمْ أَجْرًا فَهُم مِّن مَّغْرَمٍ مُّثْقَلُونَ

Or do you, [O Muḥammad], ask of them a payment, so they are by debt burdened down?

مَا ضَلَّ صَاحِبُكُمْ وَمَا غَوَىٰ

Your companion [i.e., Muḥammad] has not strayed, nor has he erred,

وَمَا صَاحِبُكُم بِمَجْنُونٍ

And your companion [i.e., Prophet Muḥammad (ﷺ) ] is not [at all] mad.
