Al-Kahf 18:24

Illa an yashaa Allahuwathkur rabbaka itha naseeta waqul AAasaan yahdiyani rabbee li-aqraba min hatha rashada

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."

unless (you say - ‘if) Allah wills.’ And remember your Lord if you forget, and say (to those who asked you about the story of the People of the Cave), “May be, my Lord will lead me to something closer than this to guidance.”
