"Or do they have the dominion of the heavens and the earth and what is between them?" It is interrogative; meaning: they possess nothing of that. "Then let them ascend"—let them rise—"through the causes [the means]." Al-Suddi said: Meaning: through the gates; the gates of the heavens, if they were able to do that; meaning: they are not able to do it.
Muhammad said: The meaning is: if they claim any of these things that none possesses but Allah, let them ascend through the means that would lead them to the heaven.
