Qur'an, Ash-Shura, Surah 42:27-29

When people have despaired of reaping a harvest, God sends down rain. He spreads his blessing across the world; he is the glorious guardian. Look at how he created the heavens and the earth, and all the creatures that he has spread across the earth. The creation is merely one among many of his signs. If he wanted, he could gather the heavens and the earth and all the creatures into one place.
