(Al-Ahraf) 7 : 99
أَفَأَمِنُوا مَكْرَ اللَّهِ ۚ فَلَا يَأْمَنُ مَكْرَ اللَّهِ إِلَّا الْقَوْمُ الْخَاسِرُونَ
Then are they secure from Lord Allah’s plotting, then no one feels secure from the plotting of Allah except the people of losers.
It is told in verse 14: 46: "Surely, they had plotted, but their plotting is with Lord, even if their plotting were enough to move the mountains!" That means, if anyone plots against the Truth, it will act back to him like a boomerang. None plots against the Truth except the losers. See explanation 3: 54 and 6: 123-124.
