How are planets and stars still being created after the six days in which Allah created the heavens and the earth and what is between them?

Allah created the heavens and the earth and what is between them in six days, as stated in the Holy Qur’an. The Qur’an and the Sunnah have detailed these days: the earth was created in two days, and its provisions were ordained in four days (including the first two days), then He rose to the heaven and fashioned them into seven heavens in two days. The creations "between them" include stars, mountains, and other things.

There is nothing in the verses to indicate that creation ceased after these six days, for Allah is the All-Creator, the All-Knowing, and He creates whatever He wills whenever He wills, as in the creation of plants, animals, clouds, and humans, and Allah will create a new creation for Paradise.
