land (in their control) from its outlying border? (Where) Allah
commands, there is none to put back His command: and He is Swift in

doings of every soul; and soon will the Unbelievers know who gets
home in the End.
[43] The Unbelievers say: "No Messenger art
thou." Say: "Enough for a witness between me and you is Allah, and
such as have knowledge of the Book."
