18. Al-Kahf (The Cave)

5. Ma lahum bihi min AAilmin wala li-aba-ihim kaburat kalimatan takhruju min afwahihim in yaqooloona illa kathiban
  

  Translation

5. No knowledge have they of such a thing, nor had their fathers. Mighty is the word that comes out of their mouths [i.e. He begot (took) sons and daughters]. They utter nothing but a lie.
