﴿ وَأَنَّهُمْ ظَنُّوا۟ كَمَا ظَنَنتُمْ أَن لَّن يَبْعَثَ ٱللَّهُ أَحَدًۭا ﴾

“so much so that they came to think, as you [once] thought, that God would never [again] send forth anyone [as His apostle].”

(And indeed they) the disbelievers of the jinn before they accepted faith (supposed, even as you suppose) O people of Mecca, (that Allah would not raise anyone (from the dead)) and it is also said that this means: and they supposed just as you did that Allah will not send anyone as a messenger.
