Ya-Sin - 36:67

وَلَوْ نَشَاء لَمَسَخْنَاهُمْ عَلَى مَكَانَتِهِمْ فَمَا اسْتَطَاعُوا مُضِيًّا وَلَا يَرْجِعُونَ
[36:67]
And if We please We would surely transform them in their place, then they would not be able to go on, nor will they return.
And if it had been Our Will, We could have transformed them (to remain) in their places; then should they have been unable to move about, nor could they have returned (after error).
And had We willed, We verily could have fixed them in their place, making them powerless to go forward or turn back.
