Nahnu khalaqnaahum wa shadadnaaa asrahum wa izaa shi'naa baddalnaaa amsaala hum tabdeelaa
We have created them and strengthened their forms, and when We will, We can change their likenesses with [complete] alteration.
1 Mufti Taqi Usmani
We have created them and have made their joints strong. And whenever We will, We would replace them with others like them, a total replacement.
