And they had planned their plan, but with Allah is [recorded] their plan, even if their plan had been [sufficient] to do away with the mountains.
The Saheeh International Quran Translation
وَقَدْ مَكَرُوا۟ مَكْرَهُمْ وَعِندَ ٱللَّهِ مَكْرُهُمْ وَإِن كَانَ مَكْرُهُمْ لِتَزُولَ مِنْهُ ٱلْجِبَالُAnd they had planned their plan, but with Allah is [recorded] their plan, even if their plan had been [sufficient] to do away with the mountains.
