Surah 6. Al-An'am

9It is a nice way of cornering the mushrikin. At first Allah tells His Messenger to ask them, "Whose is all that is in the heavens and the earth?" The questioner put the question and waited for an answer. But they kept silent because their answer could neither be in the negative nor in the affirmative. They could not deny this because they themselves believed that `all belongs to Allah.' But they could not affirm this because in that case, they themselves would have supplied the adversary with an argument against their own creed of shirk. After putting them in this critical position, Allah enjoined His Messenger to say, "All belongs to Allah."
