يَنفَعُكُمْ

Appears 2 times in the Quran. (Root: نفع)
  1. And if I intend to give you good advice, my advice will not profit you if Allah intended that He should leave you to go astray; He is your Lord, and to Him shall you be returned.

  2. He said: What! do you then serve besides Allah what brings you not any benefit at all, nor does it harm you?
