Al-Kahf · 18:14

14. And I strengthened their hearts with faith and firmness on it, and to be patient in leaving one’s homeland for its sake, when they stood to proclaim their faith in Allah alone in front of the disbelieving king, and they said: The Lord I believe in and worship is the Lord of the heavens and earth. I will never worship the gods you have falsely claimed besides Him. I will have said an unjust and far-off statement if I worship others besides Him.
