Surah Al-Insan — Ayah 28 (76:28)
نَّحۡنُ خَلَقۡنَٰهُمۡ وَشَدَدۡنَآ أَسۡرَهُمۡۖ وَإِذَا شِئۡنَا بَدَّلۡنَآ أَمۡثَٰلَهُمۡ تَبۡدِيلًا ٢٨
English translation (Saheeh International)
We have created them and strengthened their forms, and when We will, We can change their likenesses with [complete] alteration.
Brief commentary
I have created them and strengthened their creation by giving strength in their joints, limbs etc. And if I wanted to destroy them and replace them with people like them, I would have done so.
