Surah Al-Kahf Ayahs #28 Translated in English

Except [when adding], "If Allāh wills." And remember your Lord when you forget [it] and say, "Perhaps my Lord will guide me to what is nearer than this to right conduct."

And they remained in their cave for three hundred years and exceeded by nine.

Say, "Allāh is most knowing of how long they remained. He has [knowledge of] the unseen [aspects] of the heavens and the earth. How Seeing is He and how Hearing! They have not besides Him any protector, and He shares not His legislation with anyone."

And recite, [O Muḥammad], what has been revealed to you of the Book of your Lord. There is no changer of His words, and never will you find in other than Him a refuge.

And keep yourself patient [by being] with those who call upon their Lord in the morning and the evening, seeking His face [i.e., acceptance]. And let not your eyes pass beyond them, desiring adornments of the worldly life, and do not obey one whose heart We have made heedless of Our remembrance and who follows his desire and whose affair is ever [in] neglect.
