(Furqan) 25 : 55
وَيَعْبُدُونَ مِنْ دُونِ اللَّهِ مَا لَا يَنْفَعُهُمْ وَلَا يَضُرُّهُمْ ۗ وَكَانَ الْكَافِرُ عَلَىٰ رَبِّهِ ظَهِيرًا
And they are serving besides Lord Allah which doesn’t benefit or harm them, and the disbeliever is the helper of evil against his Lord.
Whoever invokes anyone besides Lord Allah is not invoking except the disbeliever Satan as explained in verse 4: 117. The Fujjar who reject Adhikr are serving Satan and are following his footsteps as explained in verse 16: 36. The believer who testifies Adhikr will help Lord by conveying His Message to entire worlds, so Lord will help him back. See explanation 2: 62; 9: 32-33; 19: 44-45; 21: 66-67 and 22: 11-12.
