Translation of the verse 14 from Surah Al-Kahf : Number of verses 110 - - page 294 - Part 15.
And We made their hearts firm and strong (with the light of Faith in Allah and bestowed upon them patience to bear the separation of their kith and kin and dwellings, etc.) when they stood up and said: "Our Lord is the Lord of the heavens and the earth, never shall we call upon any ilah (god) other than Him; if we did, we should indeed have uttered an enormity in disbelief.
And We made firm their hearts when they stood up and said, "Our Lord is the Lord of the heavens and the earth. Never will we invoke besides Him any deity. We would have certainly spoken, then, an excessive transgression.
(18:14) We strengthened their hearts, when they rose up, and they declared, "Our Lord is the One Who is the Lord of the heavens and the earth. We will not invoke any other deity than Him. It will be the most improper thing if we do so" .
