The Criterion - 25:55
And they serve besides Allah those who can neither benefit nor harm them. The disbeliever is the one who disobeys his Lord.
An example for those who cannot harm or benefit themselves:
Prophet Jonah/10:18
"They leave Allah and serve those who can do them neither harm nor good, and say: "These will intercede for us with Allah". Say: "Do you inform Him of what Allah does not know in the heavens and the earth? He is Most High, far from what you associate partners with."
Prophet Jonah/10:49
"Say: "Except Allah wills, I have no power to harm or benefit even myself. Every community has a term. When their term is over, they will neither be delayed for an hour nor brought forward."
The Heights/7:188
"Say: "I can neither benefit nor harm myself except what Allah wills. Had I known the secret, I would have increased my wealth and no evil would have touched me. I am but a bearer of glad tidings and a warner to a people who believe."
The Jinn/72:21
"Say, "I am not able to do you any harm or benefit."
Ta-Ha/20:88
"He raised for them the image of a braying calf. They said: "This is your God and the God of Moses, but he (Moses) forgot"."
Ta-Ha/20:89
Did they not see that he could give them no answer, nor could he do them any harm or benefit?
The Poets/26:70
"He said to his father and his people, "What do you serve?"
The Poets/26:71
"They said: "We serve the statues; we are devoted to them"."
The Poets/26:72
"He said, "Do they hear you when you call them?"
The Poets/26:73
Or are they able to benefit or harm you?
