﴿ وَلَبِثُوا۟ فِى كَهْفِهِمْ ثَلَٰثَ مِا۟ئَةٍۢ سِنِينَ وَٱزْدَادُوا۟ تِسْعًۭا ﴾

“AND [some people assert], "They remained in their cave three hundred years"; and some have added nine [to that number].”

(And (it is said) they tarried in their Cave three hundred years and add nine) before Allah made them wake up.
