وَلَبِثُوا فِي كَهْفِهِمْ ثَلَاثَ مِئَةٍ سِنِينَ وَازْدَادُوا تِسْعًا
[18:25]
And they remained in their cave three hundred years and (some) add (another) nine.
So they stayed in their Cave three hundred years, and (some) add nine (more)
And (it is said) they tarried in their Cave three hundred years and add nine.
