﴿ وَمِنْهُم مَّن يُؤْمِنُ بِهِۦ وَمِنْهُم مَّن لَّا يُؤْمِنُ بِهِۦ ۚ وَرَبُّكَ أَعْلَمُ بِٱلْمُفْسِدِينَ ﴾

“And there are among them such as will in time come to believe in this [divine writ], just as there are among them such as will never believe in it; and thy Sustainer is fully aware as to who are the spreaders of corruption.”

And of them that is of the people of Mecca are some who believe in it God being aware of this in their case and some who would never believe therein. And your Lord knows very well the corrupters this is a threat for them.
