﴿ أَمْ يَقُولُونَ تَقَوَّلَهُۥ ۚ بَل لَّا يُؤْمِنُونَ ﴾

“Or do they say, “He himself has composed this [message]”? Nay, but they are not willing to believe!”

(Or say they) indeed the disbelievers of Mecca say: (He hath invented it?) Muhammad lies and has invented the Qur'an. (Nay, but they will not believe) in Muhammad (pbuh) and the Qur'an as in Allah's pre-eternal knowledge!
