Al-Furqan 25:55

WayaAAbudoona min dooni Allahi mala yanfaAAuhum wala yadurruhum wakanaalkafiru AAala rabbihi thaheera

But they worship rather than Allāh that which does not benefit them or harm them, and the disbeliever is ever, against his Lord, an assistant [to Satan].

They worship, instead of Allah, what can neither give them any benefit nor can cause them any harm. The disbeliever is always a supporter (of Satan) against his Lord.
