Al-Haqqah 69:43

إِنَّهُ لَقَوْلُ رَسُولٍ كَرِيمٍ

[That] indeed, the Qur'an is the word of a noble Messenger.

وَمَا هُوَ بِقَوْلِ شَاعِرٍ ۚ قَلِيلًا مَّا تُؤْمِنُونَ

And it is not the word of a poet; little do you believe.

وَلَا بِقَوْلِ كَاهِنٍ ۚ قَلِيلًا مَّا تَذَكَّرُونَ

Nor the word of a soothsayer; little do you remember.

وَلَوْ تَقَوَّلَ عَلَيْنَا بَعْضَ الْأَقَاوِيلِ

And if Muhammad had made up about Us some [false] sayings,

لَأَخَذْنَا مِنْهُ بِالْيَمِينِ

We would have seized him by the right hand;

ثُمَّ لَقَطَعْنَا مِنْهُ الْوَتِينَ

Then We would have cut from him the aorta.
