Translation:

19. See they not how Allah originates creation then repeats it: truly that is easy for Allah.

Notes (Tafseer)

3440. The originating of creation is the creation of primeval matter. The repetition of the process of creation goes on constantly, for at every moment new processes are being called into being by the creative power of Allah, and according to His Laws. And the final creation as far as man is concerned will be in the Ma'ad, when the whole world as man sees it will be entirely newly created on a different plane. As far as Allah is concerned, there is nothing final, no first and last, for He is infinite. He was before our First and will be after our Last.
