﴿ إِنَّهُۥ لَقَوْلُ رَسُولٍۢ كَرِيمٍۢ ﴾

“behold, this [divine writ] is indeed the [inspired] word of a noble apostle,”

(That this) i.e. the Qur'an (is in truth the word of an honoured messenger) Allah says: it is brought down by Gabriel to a messenger who is honoured by Allah, i.e. Muhammad (pbuh)
